Answer:
Explanation:
First consider the equation for the slope. m = (y2 - y1)/(x2 - x1) = (1 - 8)/(6 - 4) = -7/2.Next consider the linear point-slope formula y = mx + b. Choose a point and plug it in (either will do, the result will be the same). 1 = (-7/2)(6) + b = -21 + b -> b = 22 - > y = (-7/2)x + 22 is the equation you desire.
