Question

Find a slope of a line that passes through the points (0,-4) and (-3,2)

Answer 1

y = -2x - 4

Explanation:

As we go from (0, -4) to (-3,2), x decreases by 3 and y increases by 6. Thus, the slope is m = rise / run = 6/(-3) = -2.

The equation of the line is y + 4 = -2(x - 0), or

.

Answer 2

The slope is -2

Explanation:

The formula for slope. which is the change in y over the change in x is given by

m = (y2-y1)/ (x2-x1)

= (2--4)/(-3-0)

= (2+4)/(-3-0)

= 6/-3

= -2
