Question

Find the slope and y-intercept from the following graph of a linear equation.

Answer 1

For this question, you need to find the slope-intercept form of the graph. To do this, start with two points and plug them into y2-y1 / x2-x1.

(-1,-1)(1,7)

7 - - 1 / 1 - - 1 = 8/2 = 4

Therfore, your slope is 4

Next, the y-intercept. This is the point where the graph crosses with the y. In this problem, the lines intercept at the point (0,3).

Therefore, your y-intercept is 3

Y-intercept = 3, Slope = 4

Slope-Intercept form is y = 4x + 3
