Write in slope-intercept form an equation of the line that passes through the given points.
(−1,4),(3,8)
Answers
step by step explanation:
Answer:
y = x + 5
Step-by-step explanation:
Slope (m) formula: [tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]
[tex]m=\frac{y_2-y_1}{x_2-x_1}\\\\m=\frac{8-4}{3-(-1)}\\\\m=\frac{8-4}{3+1}\\\\m=\frac{4}{4}\\\\m=1[/tex]
y = mx + b
y = 1x + b OR y = x + b
(-1, 4)
y = x + b
4 = -1 + b
+1 +1
5 = b
y = x + 5
Check your answer using y = x + 5 and (3, 8):
y = x + 5
8 = 3 + 5
8 = 8
This statement is true
Therefore, our final answer is, y = x + 5.
Hope this helps!

Answers
Answer:
This online sales tax calculator solves multiple problems around the tax imposed on the sale of goods and services.
Answer:
$1.6
Step-by-step explanation:
If 8% is charged for each $. Tax charged for $1 = 8/100 which is equal to 0.08.
Tax Amount payed
$0.08 -----------> $1
$y ------------> $20
This is directly proportional. Therfore cross multiply the values.
y × 1 = 20 × 0.08
y × 1 = 1.6
y = 1.6/1
y = 1.6
Therefore $1.6 is the amount of tax charged for $20

formula for rectangle: length * width
17 * 3 + 2* 951 + 1869Answer:
The upright rectangle is the shape we're going to find the area of first;
Formula for area of rectangle;
A = BH
where b is the base, and h is the height
plug in the actual values:
A = BH
A = 17(3)
A = 51
Now let's find the area of the rectangle below;
Using the formula we applied to the upright rectangle;
A = BH
Though first, we need to find the height.
The total height of the two rectangles combined is 17, the height of just the upright rectangle is 15. So we subtract the two to get the height of the bottom rectangle, (17 - 15) = 2
A = 9(2)
A = 18
Now we add both of their sums;
51 + 18 = 69 ft^2, is your answer.
On a math test a student, Sarah, has to identify all the coefficients and constants of the expression 6n + 5 +m. Sarah says that is a coefficient and 5 is a constant. Identify all the coefficients and constants of the expression. What error might Sarah have made?
Answers
Hi! I hope you're enjoying your day!
A coefficient is a number before a variable. (for example, 12d)
A variable is a letter (for example, a)
A constant is a number with no variables (not 6s, but 6)
Let's identify the coefficients & the constants here.
We have the expression
[tex]\bold{6n+5+m}[/tex]
And we know that a coefficient is a number before a variable.
So we know the coefficient (6)
Now, a constant is a number with no variables multiplied by it (or divided by it)
Hence, the answer is
[tex]\boxed{\boxed{\bold{coefficient-\:6\:;constant\:-5\:and\:Sarah's\;right}}}[/tex]
Hope everything is clear.

A bicycle has a listed price of $811.99 before tax. If the sales tax rate is 6.5% , find the total cost of the bicycle with sales tax included.
Round your answer to the nearest cent, as necessary.
Answers
Answer:698.86
Step-by-step explanation:Bicycle - $655.95
Sales Tax 6.5% = 655.95 x 6.5% = 42.636
Total $655.95 + 42.636 = 698.858 = 698.86 - Total cost of the bicycle with sales tax included.
Sale tax is 6.5% of the value of the price which is $811.99
You need to find the value of tax then added to $811.99 which is $52.77 ( 811.99x6.5)/100
The total price including tax is $811.99 + 52.77 = $864.76

John keeps track of his father's driving to pass the time on a trip to Grandma's. He records the distance each hour, and he will graph the results. If the pattern of mileage change continues, how far will they have driven in 11 hours?

1 70 (1, 70)
2 140 (2, 140)
3 210 (3, 210)
4 280 (4, 280)
560 miles
700 miles
350 miles
770 miles
Answers
Answer:
770 miles
Step-by-step explanation:
First, find the slope (m) of the pattern, using any two points from your data set.
Slope (m) = [tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]
(1, 70) and (3,210)
[tex]m=\frac{y_2-y_1}{x_2-x_1}\\m=\frac{210-70}{3-1}\\m=\frac{140}{2}\\m=70[/tex]
y = mx + b
y = 70x + b
(1, 70)
y = 70x + b
70 = 70(1) + b
70 = 70 + b
-70 -70
0 = b
y = 70x + b OR y = 70x
Now we find how he has driven in 11 hours
y = 70x
y = 70(11)
y = 770
Therefore, he will have driven 770 miles in 11 hours.
