Question

Write an equation the line passes through (4, 1) and is parallel to y = - 2x + 7

Answer 1

y = -2x + 9

Explanation:

The equation of the new line is the same as that of this given line, EXCEPT that the constant will be different.

Start with y = mx + b; substitute 1 for y, 4 for x and -2 for m:

1 = -2(4) + b

Then b = 9, and y = -2x + 9
