By definition, the Slope-Intercept Form of the equation of a line is:

Where "m" is the slope and "b" is the y-intercept.
Then, to find the slope and the y-intercept of the line given in the exercise, you only need to solve for "y", in order to write the equation in Slope-Intercept Form:

Now you can identify that the slope is:

And the y-intercept is:

Therefore, the answer is:

3+7=10
7+3=10
8+2=10
17-7=10
Quotient means that division was used so you do the opposite of division which is multiplication... so you do 12×2 and get 24 ...so 24 fast songs were played
