You combined the x’s together then u wanna move all the x’s to one side then after that you would want to do the opposite of -7, so then you add 7 to 10 and then you would divide everything by 2 and get x=8.5
Answer:
y=3x-2
Step-by-step explanation:
The formula for slope is y=mx=b
You can find the slope by finding two points that lie on the line (1,1) & (0,-2)
The formula for slope is 
You plug the values in and you get 
Simplify and you get 3
The slope is 3
The y-intercept (b) is -2
r-12
substitute in r=7
so 7-12 = -5
It is a knowledge check
