Y=mx+b
m=0.5
b is value of y in y-intercept, b=-2
The equation of this line is
y=0.5x-2
When x=4
y=0.5x-2=y=0.5*4-2=2-2 = 0
When x=4, y=0.
We have no factors to go by
Wait, do you want me to solve for x or for y??
For y it's,

For x it's,
Answer:
-3 over 7 or -0.429
Step-by-step explanation:
8 -6g + 15 = 19
You want to isolate the terms (separated by +) that doesn't have letters next to it, to the other side.
So, get 8 and 15 to the other side by subtracting both sides. They don't have letters next to them.
-6g =-4
Divide the -6 on both sides to get "g" alone.
g = 4/6
Simplify
g= 2/3
