Question

Find the slope and the y−intercept of the line in the graph.

The slope is .

The y−intercept is .

Can anyone help me?

Answer 1

• slope: 5
• intercept: 4

Explanation:

It works well to find the slope using points where the graph crosses grid intersections. We see two of those are (0, 4) and (1, 9). The slope formula tells us ...

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

m = (9 -4)/(1 -0) = 5

The slope is 5.

The y-intercept is the value of y when x=0. The point (0, 4) tells us ...

The y-intercept is 4.
