Answer:
u = 10
Explanation:
slope can be calculated using the following rule:
slope = (y2-y1) / (x2-x1)
We are given:
slope = -4/3
point (10,6) representing (x1,y1)
point (7,u) representing (x2,y2)
Substitute with the givens in the above rule and solve for u as follows:
slope = (y2-y1) / (x2-x1)
-4/3 = (u-6) / (7-10)
-4/3 = (u-6) / (-3)
-3 * -4 = 3 * (u-6)
4 = u - 6
u = 4 + 6
u = 10
Hope this helps :)
