Question 1043787: Find the equation of a line in slope-intercept form that passes through the points (-2, 20) and (3, -10).

You can put this solution on YOUR website! The formula for a line in slope intercept form is
:
y = mx + b, where m is the slope of the line and b is the y intercept
:
we are given two points on the line, (-2, 20) and (3, -10)
:
m = (y2 - y1) / (x2 - x1) = -10 -(20) / (3 -(-2)) = -6
:
we pick one of the two points, say (-2, 20)
:
20 = -6(-2) + b
:
b = 8
:
****************
y = -6x + 8
