Answer:
=4x+12
Step-by-step explanation:
Distribute:
=−8x+(4)(3x)+(4)(3)
=−8x+12x+12
Combine Like Terms:
=−8x+12x+12
=(−8x+12x)+(12)
=4x+12
Answer:

Answer:
y = 2x - 6
Step-by-step explanation:
Slope-intercept form is y = mx + b, where m is the slope and b is the y-intercept.
The y-intercept is already given and is -6.
By c intercept, I am assuming you meant x-intercept. With an x-intercept of 3, the point is (3,0). With a y-intercept of -6, the point is (0,-6).
Use the two points to find the slope using the following equation.

Plug the points into their respective positions and solve.

The slope is 2.
Your equation is y = 2x - 6.
8 × 46 = 8 × (40 + 6) = (8 × 40) + (8 × 6) = 320 + 48 = 368
