Y=MX+B
M = slope
B = y intercept (number that intersects with the line in the y axis)
y=-3/4x+2
It starts on the y intercept (2) then we travel to the next point (4 on the x axis)
So we travel 3 spaces down (-3) landing on the origin (0,0) then four spaces to the right (4). Getting the slope of -3/4 (rise over run)
Then just plug in these into the equation
y = -3/4 + 2
The answer is -- 8 hours
Explanation:
8 (tip) x 6 (tables) = $48
104 - 48 = $56
56 / 7 = 8
47/15 in its simplest form would be 2/15
