Answer:
(4x-32),-2,1-13)6
Step-by-step explanation:
First find the slope, (y2-y1)/(x2-x1)=(20-10)/(40-20)=10/20=1/2
y=mx+b, where m is the slope and b is the y-intercept
y=x/2+b, using any point we can solve for b, I'll use (20, 10)
10=20/2+b
10=10+b
0=b, so the cost function is:
C(m)=m/2 (cost in dollars as a function of minutes is minutes divided by two)

Answer:
Step-by-step explanation:
y = 2x
when x = 1
y = 2(1).....y = 2........so when x = 1, y = 2
when x = 2
y = 2(2)....y = 4 ......so when x = 2, y = 4
when x = 3
y = 2(3)....y = 6.......when x = 3, y = 6
when x = 4
y = 2(4).....y = 8.....when x = 4, y = 8
============================
y = 4x - 1
when x = -4
y = 4(-4) - 1.....y = -17.....so when x = -4, y = -17
when x= -3
y = 4(-3)- 1..... y = -13....so when x = -3, y = -13
when x = -2
y = 4(-2) - 1.....y = -9.....so when x = -2, y = -9
when x = -1
y = 4(-1) - 1....y = -5.....so when x = -1, y = -5
you can make the tables from this info...
your basically just subbing in ur value of x into the equation to find ur value of y
