The answer is y-4=3[(x-(-4)]
This is because of the formula y-y1=m(x-x1)
The second sentence doesnt really make sense to me, it sounds incomplete but, I may be wrong. His total not including whatever it says in the second sentence is $64. I hope this may help a little bit.
4.
A slope is the steepness of the line, rise over run, change in y over change in x
A translation is a type of transformation that moves each point in a figure the same distance in the same direction (up, down, left right).
5. reflection on y-axis
6. vertical translation & horizontal translation
7. horizontal translation & vertical stretch
8. vertical translation & Horizontal stretch
9. vertical translation & horizontal translation & reflection over the x-axis & horizontal translation
10. vertical translation & horizontal stretch
HOPE THIS HELPS!
Function B has a rate of change ( or slope) of 11-5 / 3-1 = 6/2 = 3
Function L y = 6x + 4 has a rate of change of 6 . Higher than function B.
To find y intercept of function B;
y = 3x + b where b = y intercept, when x = -3 y = -7 so
-7 = 3(-3) + b giving b = 2
y intercept of Function B is 2 and of function L it is 4
L has greatest y intercept
