Answer:
y = 2x + 4
Step-by-step explanation:
Two points on this line are (-2, 0) and (0, 4). Going from the first to the second, x increases by 2 (this is the 'run') and y increases by 4 ('rise').
Thus, the slope of this line is m = rise / run = 4/2 = 2
Using the slope-intercept formula, we get y = mx + b = 2x + b
Let x = -2 and y = 0 to find b: 0 = 2(-2) + b, so b = 4, and the desired equation is then:
y = 2x + 4
Answer:
1/2 ÷ 4 = 8
Step-by-step explanation:
Dividing fractions is as easy as pie. Flip the second and multiply.
1/2 ÷ 4 = 1/8
A whole number secretly has a 1 underneath, like this: 4/1
Flip the second number over to get 1/4, then multiply straight across.

Answer:
It has to be 4-7
Step-by-step explanation:
Answer:
4
Step-by-step explanation:
256 = x^4
Take the 4th root of both sides.
4^√256 = 4^√x^4
<u>4 = x</u>
