Answer:
b. 28x + 8y +2
Step-by-step explanation:
you need to distribute the -2 to all the numbers inside parentheses and then combine like terms.
-2*3x= -6x
-2*12y= -24y
-2*-5= 10 (remember neg times neg = pos)
-2*17= 34x
-2*-16y=32y
-2*4= -8
Now combine like terms
34x-6x= 28x
32y-24y=8y
10-8=2
Write the expression: 28x + 8y +2
Answer:
B, y = 4x + 1
Step-by-step explanation:
to get it into y- intercept form we need to write it in the form y = mx + b
-8x = 2 - 2y, move 2y to the other side and -8x to the other side they both become positive.
2y = 8x + 2, dividing each by 2
yields y = 4x + 1
Hope this helps
