The y values are the same, so there cannot be a slope. The (mx) part of y=mx+b is cancelled out, and is left with the b. Since the y value is forever three, the y-intercept will be 3 as well.

Therefore, the slope-intercept equation is

y=3

Airida [17]

Let x be the number of song points.
Let y be the number of videos points.

We have the first expression:
5x + 7y = 295

We have the second expression:
10x + 3y=150

Solve for y and x:
x = (295 -7y)/5
10 ((295-7y)/5) + 3y = 150
590 - 14y + 3y =150
590 - 150 = 14y -3y
y=40 points

solving for x:
x = (295-7*40)/5
x=3 points/song

If she buy, all songs for 333 points
number of songs = 333 / 3
number of songs = 111

The answer is 111.
