Answer:
-9x+12
Step-by-step explanation:
(-8x + 5) - (x – 7)
Distribute the minus sign
(-8x + 5) - x + 7
Combine like terms
(-8x -x+ 5+7)
-9x +12
Let the score on her seventh test be "x".
SO,

∴ He must get 104% on his seventh test to get an average score of 90%

Answer:
See attached graph
Step-by-step explanation:
The equation is y-3=(x + 6)
Write the equation in a slope intercept form, then graph the equation on a graph tool to see the points that line on the line.
Alternatively , using the coordinates in the answer choices given, input them in the equation of the graph and select the answer choice that has all its coordinates true to the equation.
y-3 = x+6 -----can be written as : y= x+9
Graph y= x+9 to see the graph and the points that are on the line as attached.
