Find the Slope between two points: (-1,9) and (2, 3)
Answer:
Slope = -2
Step-by-step explanation:
x1 y1 x2 y2
(-1 , 9) (2 , 3)
Slope = y2 - y1
x2 - x1
3 - 9 = -6
2 -(-1) = 3
= -2
The slope between the two points is -2.
What is an equation of a line?The equation of a line is given by:
y = mx + c
where m is the slope of the line and c is the y-intercept.
Example:
The slope of the line y = 2x + 3 is 2.
The slope of a line that passes through (1, 2) and (2, 3) is 1.
We have,
The slope is given as,
m = (d - b) / (c - a)
Where (a, b) and (c, d) are the two points.
Now,
(-1, 9) = (a, b) and (2, 3) = (c, d)
m = (3 - 9) / (2 + 1)
m = -6 / 3
m = -2
Thus,
The slope is -2.

Answer:
B. 66
Step-by-step explanation:
idk how to explain it without repeating what it says in the answer
Answer:
The answer is:
B) 66 degrees
Step-by-step explanation:
Since the triangle is an isosceles triangle, angle C is the same as angle B.
57 + 57 = 114
Since you know two of the three angles, and you know that a triangle's angles must equal 180 degrees...
180 - 114 = 66
Angle A must equal 66 degrees for the triangle to equal 180 degrees.

If the given equations are y=3x+14 and y= -4x. The value of x and y for the equation will be -2 and 8 respectively.
What is an equation?Equations are statements that affirm the equivalence of two expressions that are joined by the equals symbol "=". An equal sign ("=") links two expressions together to form an equation. The two expressions on each side of the equals sign are referred to as the "left-hand side" and "right-hand side" of the equation.
It is given that the equations are,
y=3x+14 ----------(1)
y= -4x -------------(2)
In order to solve "by substitution," you must first solve one of the equations for one of the variables (you choose which one), plug that solution back into the other equation, "substituting" for the selected variable and then solve for the other.
Substitute the value of y from equation 2 in equation 1 as
y=3x+14
-4x=3x+14
Rearrange the equation in order to find the value of x as
-4x-3x=14
-7x=14
x= -14/7
x= -2
Put the value of x in equation 2 as
y= -4x
y= -4(-2)
y=8
Thus, if the given equations are y=3x+14 and y= -4x. The value of x and y for the equation will be -2 and 8 respectively.
