Answer:
x=8
Step-by-step explanation:
When trying to figure this out, you may see that x might be 8. Since the angels are all 120 degrees and equal up to 360 degrees (full size,) x will equal 8.
Well just by looking at the information provided, you can tell that the equation would look like y = 4x -1. The y-intercept is -1 because the x value is 0. But if you want to see how to solve it algebraically, here’s an explanation... You need to substitute the y-intercept into the equation in order to solve for b, which would then complete the equation. Take the equation y=mx+b. Substitute in the slope and xy values, (-1) = 4(0) + b. Now the equation should look like this: -1 = b. So now that you have the value of b, the complete equation should be y=4x-1
Answer:
1/3, -7
Step-by-step explanation:
Before answering this, I will need to assume that you actually meant
y = (1/3)x - 7. Comparing this to y = mx + b, we see that the slope, m, is 1/3 and the y-intercept, b, is -7.
