Question

-10x+300=0 find x and y intercept

Answer 1

The y-intercept is 300, and to find the value of x you solve for x.
-10x + 300 = 0
- 300 -300
-10x = -300
Divide both sides by -10
x = 30
Now to check our work:
-10(-30) +300 = 0
-300 + 300 = 0

Answer 2

I know this is a bit late but the 30 is not supposed to be a negative sorry. It should look like this:
-10(30) + 300 = 0
-300 + 300 = 0
0 = 0
