Question

Write the slope-intercept form of the line that passes through the point (1, 0) and is parallel to x - y = 7.

Answer 1

First step: Put x - y = 7 into slope-intercept form.

Answer 2

line is parallel to the line x-y = 7 so slope of the line is 1

Answer 3

now the slope intercept equation can be written as
(y - 0) = slope (=1) (x-1)
y=x-1

Answer 4

So it's y=x-1?
