Answer:
22.5 or 360
(PLEASE READ THE EXPLANATION BELOW!!!)
Step-by-step explanation:
So, all we have to do is plug in the variables in the equation: y = mx+b
So, y is 100, b is 10, and m is 0.25 or 1/4.
100 = 1/4x + 10
100 = (1/4 x 22.5) + 10
So, x would be 22.5.
(This would be the basic algebraic answer. Now, if we were trying to find the x-intercept, that would be a different problem.)
If you are trying to find the x-intercept of the equation, then the answer would be 360 [as in (0, 360)]
Step-by-step explanation:
Givens:
slope intercept form: y=m*x+b
where y=100, b=10, and m=0.25
solve for x
1) y=mx+b
2) y-b=mx
3) (y-b)/m=x
4) (100-10)/0.25=x
x=360
