Question

How can you find the x-intercept of the graph of a linear equation?A. Substitute x = 0 into the equation and solve for y.B. Substitute y = 0 into the equation and solve for x.C. Substitute x = 1 into the equation and solve for x.D. Substitute y = 1 into the equation and solve for y.

Answer 1

Answer:

B. Substitute y = 0 into the equation and solve for x.

Explanations:

A linear equation takes the form:

y = mx + c

Where m is the slope

and c is the intercept

To find the x intercept of the graph of a linear equation, substitute y = 0 into the linear equation, y = mx + c, and solve for x.

0 = mx + c

mx = -c

x = -c / m
