Question

y = 0.75x y = 10 + 0.50x

Answer 1

I'm assuming you want this solved for x. To do that, set the two y values against each other in an equation, then solve algebraically.

.75x = 10 + .50x      Subtract .50x from both sides.
.25x = 10                 Divide both sides by .25
     x = 40

Answer 2

If your trying to find slope, then


your 10 is your slope intercept, that turns into the coordinates (0,10)


after that you put 0.50 into the coordinate (0.50,10)


this is what I THINK is how to solve for slope, I'm not 100%

but I'm sure it is correct 80%
