Question

Write an equation that is parallel to line y=x-5 through (1, -2)

Answer 1

y = x - 3

Explanation:

y = mx + b

m is slope of a line, because the line is parallel to the line y = x - 5, slope should be the same, so m = 1

y=1*x + b

To find b, we have the point (1, -2)

-2 = 1 +b

b = -3

So line has the equation y=x - 3.
