Answer:
c 3
Step-by-step explanation:
the y intercept is where the line crosses the 0 x-axis
So ask yourself, what is the y when the x is 0?
on this one, the line crosses the 0 x-axis at 3 y
when the x is 0, the y is 3
So thats the y intercept
So you start in 0 and then cout back 3 times unyill you get to - 15 and that is how you use the number line for this problem
Answer:
0.14mph
Step-by-step explanation:
Answer:
infinite number of solutions
Step-by-step explanation:
Work with the second equation. Subtract 8x from both sides.
- 4y + 8x - 8x = -8x - 12 Collect like terms.
-4y = - 8x - 12 Divide by - 4
-4y/-4 = - 8x/-4 - 12/-4
y = 2x + 3
That is exactly the same line as the first given. There is an infinite number of solutions.
