Input the equation of the given line in slope intercept form. The line through 1,0 and parallel to x-y=7

X - y = 7

y = x - 7 ... the slope here is 1. A parallel line will have the same slope.

y = mx + b

slope (m) = 1

(1,0) ... x = 1 and y = 0

now we sub and solve for b, the y int

0 = 1 (1) + b

0 = 1 + b

-1 = b

so ur parallel line is : y = x - 1
