Question

What is the slope, m, and y-intercept for the line that is plotted on the grid below? On a coordinate plane, a line goes through points (0, 4) and (negative 2, 0).

Answer 1

Slope is 2 and y intercept is 4

Explanation:

First, we need to calculate the slope

To calculate the slope, we use the equation below;

m = (y2 - y1)/(x2-x1)

where (x1,y1) = (0,4)

and (x2,y2) = (-2,0)

Plugging these values we have

m = (0-4)/(-2-0) = -4/-2 = 2

Wondering what our y-intercept is?

The y intercept is that value at which x = 0

Now, looking at the First point we can see that when x was 0, y was 4

This makes 4 our y intercept
