Question

Which equation represents a line with a slope of 4 that passes through the point (1, 3)?

A. = 4 − 11
B. = 4 − 1
C. = 4 + 7
D. = 4 + 13

Answer 1

y = 4x - 1

Explanation:

The line has a slope of 4.

And passes through the point (1,3)

Taking another point (x,y) on the line;

`(y - 3)/(x - 1)` = 4

y - 3 = 4x - 4

y = 4x - 4 + 3

y = 4x - 1
