Question

Find the slope of the line that contains the

point (4, −9) and has a y intercept of 2.

Answer 1

m = -¹¹/₄

Explanation:

The equation of a line with slope of m and y-intercept of b is: y = mx + b

b = 2 and line contains the point (4, -9), so:

-9 = m×4 + 2 {subtract 2 from both sides}

-11 = 4m {divide booth sides by 4

m = -¹¹/₄
