Answer:
y = -8x + 4
Step-by-step explanation:
Using the y = mx +b for the slope intercept form, the m stands for the slope and the b stands for the y-intercept.
In this case, the slope is -8 and the y-int is 4 so we naturally plug those in
Answer:
y = 7
Step-by-step explanation:
3 × (3y - 4) = 51 multiply 3 with inside the parenthesis
9y - 12 = 51 add like terms
9y = 51 + 12
9y = 63
y = 7

Answer:
-0.25
Step-by-step explanation:
need to find the halfway point (average) between -0.75 and 0.25 (same as 1/4)
