Question

Line AB passes through points A(-6,6) and B(12,3). If the equation of the line in slope-intercept form,

Y = mx + b, then m = -1/6 and b=?

Answer 1

The intercept is 5.

Explanation:

Since we already have the slope of -1/6, we can use that and either point in point-slope form to get the equation in slope-intercept.

y - y1 = m(x - x1)

y - 3 = -1/6(x - 12)

y - 3 = -1/6x + 2

y = -1/6x + 5

Therefore, b= 5
