According to the y-intercept form equation : y=mx+b, and m=slope, you can find the slope just by looking at the equation.
y=mx+b
y=7x+2
notice that 7 replaces m, which means m=7
Therefore slope is 7
Hope this helps!
This is not an algebraic response
Notice that 8 is 23 and 125 is 53
So, the blank should have 54/24 which will be 5000/2000 which is equal to 5/2
Hope this helps :D
