Answer:
y = 10/9x - 46/4 OR y = 10/9x -15.3
Explanation:
1. Find the slope of the points (change in y over the change in x)
(174, 178)
(165, 168)
10/9
2. Plug into y = mx + b to find the y-intercept of the equation (I am using point 165, 168)
168 = 10/9(165) + b
3. Solve
168 = 10/9(165) + b
168 = 550/3 + b
-46/3 = b OR -15.3 = b
3. Plug in the slope and the y-intercept into y = mx + b
y = 10/9x - 46/4 OR y = 10/9x -15.3
