Question

Write the equation of a line in slope-intercept form that is parallel to x-y-1 = 0, but passes through

the point (2,-5). Graph both lines.

Answer 1

y = x - 7

Explanation:

x - y - 1 = 0

y = x - 1 .... y = mx + b

m = 1 parallel line has same slope

for (2, -5) m = 1 b = y - mx = -5 - 1x2 = - 7

equation: y = x - 7
