Answer:
y = 5x
Step-by-step explanation:
1. The slope-intercept form of any linear equation is , where y = y-coordinate, m = slope, x = x-coordinate, and b = y-intercept.
2. To find the slope, let's take the two points (0,0) and (100,500) to then plug their values in this formula:
3. Okay, great! Now that we have our slope, the equation, so far, looks like this: y = 5x + b.
4. Because b is the y-intercept, b will equal 0 because the line intersects with the y-axis at the coordinate (0,0).
Therefore, our equation is y = 5x.
Y = ![3\sqrt[3]{3}](https://tex.z-dn.net/?f=%203%5Csqrt%5B3%5D%7B3%7D%20)
81 is the same as 3 x 3 x 3 x 3. Therefore we can take out three of the four 3s and leave one inside the cube root radical.
