Answer:
The correct answer is B) y = 2x - 1
Step-by-step explanation:
To find this, first choose any two data points and find the slope. We'll use points (-2, -3) and (0, 1)
m(slope) = (y2 - y1)/(x2 -x1)
m = (1 - -3)/(0 - -2)
m = 4/2
m = 2
Now we use either point and the slope in point-slope form to get the equation.
y - y1 = m(x - x1)
y - 1 = 2(x - 0)
y - 1 = 2x
y = 2x + 1
Answer:
Step-by-step explanation:
Bill + 220
Total is 538 so subtract 220 which gives you 318.
318/2 = 159
159+220 for Bill = 379
Bob has 159
Add 159 + 220 for Bill and 159 for bob = 538
So Bill has 379
and Bob has 159
First, we divide the amount of tip which is $16 by the amount that is used to pay the food bill which is $80. Then, multiply the quotient by 100%. Mathematically,
($16 / $80) x 100% = 20%
Thus, you left 20% of the food bill for the tip.
