Question

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

Answer 1

Anything parallel to x - y = 7 will be in the form `x - y = C` where C is any constant

to find the value of C, plug in (x,y) = (1,0) which is the given point

x - y = C
1 - 0 = C
1 = C
C = 1

so we have x - y = 1 after replacing C with 1

Now solve for y in x - y = 1
