Answer:
Step-by-step explanation:
Step 2: 2.8z - 3.4z - 7.2 + 6.6
Step 3: -0.6z - 0.6
-7 (-15w + 21) + 3(18 - 27w)
step 1: 105w - 147 + 54 - 81w
You can find the slope and y-intercept, and make an equation in slope- intercept form and them just plug in the other x values in the equation.
I think we need a coordinate grid for that,,
The answer is definately A
Y=1x-7 is the equation and -7 is the value of B
