Which statements accurately describe how to determine the y-intercept and the slope from the graph below?

On a coordinate plane, a line goes through points (0, negative 6) and (3, 0).

Answer:

summary

Step-by-step explanation:

Answer: Choice C

To find the y-intercept, begin at the origin and move vertically to the graphed line. To find the slope, use two ordered pairs on the line and substitute into the equation m = (y2-y1)/(x2-x1)

============================================

Explanation:

The y intercept is where the graph crosses the vertical y axis. So that's why we move vertically from the origin to get to the graph.

The slope is calculated as the difference of y values over the difference in x values. We subtract in the same order for both. In other words,

slope = rise/run = (change in y)/(change in x)

Positive slope means the line goes uphill when you move from left to right. Negative slope means the line goes downhill when you move from left to right.

This is a simple graph, but I want to know if I’m right. If the line goes through the origin does that automatically mean it’s positive?
And when it doesn’t go through the origin does that mean it’s automatically negative?
THANK YOU.!

Answers

Answer: This is a negative graph and it is proportional because it goes through the origin.

Step-by-step explanation:

Just beacause it goes through the origin does not mean it will be positive nor negative, if the line goes from the top left of the grid slanted down, it is negative. If the line goes from the top right of the graph slanted down, it is positive. It is proportional because it is a straight line that goes through the origin.

Answer:Under↓↓↓

Step-by-step explanation:

Ok so in this case it's a negative slope, because the line is going from left to right.

If the line was going form right to left then It would be a positive slope.
