Answer:
y = -3x - .25 or y = -3x + -.25
Step-by-step explanation:
y = slope (x) + y-intercept
-4 = -3(1.25)+b
-4 = -3 .75 + -.25
-4 = -4
Answer:
w=9x+4
Step-by-step explanation:
2(3x-3+w)=12x+2
6x-6+2w=12x+2
subtract 6x for both sides
-6+2w=18x+2
add 6 for both sides
2w=18x+8
Divide by 2 to find w
w=9x+4
Answer:
4
Step-by-step explanation:
If you count by 2 two times you get 4.
