Aline with a slope of -7 passes through the points (u,0) and (8,-7) what is the value of u?

u = 7

Step-by-step explanation:

Using the slope intercept formula:

Substitute our values from the points and the known slope:

Now we multiply both sides by (8 - u) to isolate the x:

(8-u) x = -7 (8 - u)

Next we add 56 to both sides:

-7 = -56 + 7u

Finish off by dividing both sides by 7:

7u = 49

u = 7

answer: 193

explanation:

200-7 = 193
