572 rounded to the nearest 10 is 570 and 572 rounded to nearest 100 is 600.
Step-by-step explanation:

Answer:
To find the slope, you divide the difference of the y-coordinates of 2 points on a line by the difference of the x-coordinates of those same 2 points
Answer:
No.
Step-by-step explanation:
Take the second expression: 5(2 - 20)
To solve, you must distribute the 5 to all terms within the parenthesis:
5(2 - 20) = (5 * 2) - (5 * 20) = 10 - 100 = -90
On the other hand:
10 - 20 = -30
∴ the two expressions are not equivalent.
Answer:
y = 2x-4
Step-by-step explanation:
To put the equation in slope intercept form (y=mx+b), we solve the equation for y
8x = 4y +16
Subtract 16 from each side
8x - 16 = 4y+16-16
8x-16 = 4y
Divide each side by 4
8x/4 -16/4 = 4y/4
2x -4 = y
y = 2x-4
