Write an equation for the line that goes through the points (8, -4) and (0, 12)
Equation of line y = mx + b m = slope b = y-axis intercept (value of y when x = 0)
find slope (y1-y2)/(x1-x2) it does not matter which point you assign as '1' or '2'
(-4-12)/(8-0) = - 2 = m = slope
y = -2x + b now put in either one of the given points to calulate 'b'
12 = -2(0) + b b = 12
y = -2x+12
