What is ttm mean? And what do you mean by points?
Answer: two over three
Step-by-step explanation:
line intercepts y at (0,-2)
Therefore, 
Substitute x = 3 in y =ax-2
To find the x-intercept, y = 0
The slope is 2/3
y-intercept is -2
So two over three
Answer:
y=9-7x
If x= -1, y=16
If x= 0, y=9
If x=2, y= -5
Step-by-step explanation:
Because you are solving the equation for y, you want to have y by itself on one side. The only way to do that in this problem is by subtracting the 7x on both sides.
y+7x=9
-7x -7x ---> y=9-7x
The next part of the question says to find the value of Y for each value of X. Using the given X values, we plug them into the equation we just got in order to find Y.
y=9-7(-1) ----> y=16
y=9-7(0) ----> y=9
y=9-7(2) ----> y=-5
It would be -(-31) because a negative and negative is a positive
