PART A:
Solve for the slope by solving change in y over change in x. We have (3-(-5)/(-2-2) = 8/-4=-2
PART B:
Change in to y=mx+b: -5y = -2x-10. Divide all terms by -5: y = 2/5x + 2. The slope is 2/5 and the y-intercept is 2.
PART C:
Remembering from part a that m=change in y/change in x, we have the equation: -4=1-(-9)/0-x. If we simplify, we have -4=10/0-x. If we multiply both sides from 1/10 we have: -2/5 = -x. So, x = 2/5.
PART D:
We can use point-slope form first:
y-5=-7(x+1). Then we solve the equation! y-5 = -7x-7. After adding 5 to both sides, we have the equation: y=-7x-2.
Answer:
26
Step-by-step explanation:
Given that:
Target amount for NYC trip = $1000
Cost of T - shirt = $9 each
Logo printing fee = $30
Number of T - shirts = x
Number of T - shirts to be sold in other to reach their goal :
[(Cost of logo + Cost of T shirt) * number of shirts sold] ≥ target amount
[($30 + $9) * x] ≥ $1000
$39x ≥ 1000
x ≥ 1000/ 39
x ≥ 25.64
Hence, they have to sell at least 26 t shirts with logo printed to raise $1000
