Answer:
slope = 1
y-intercept = 5
Step-by-step explanation:
change in y-values = 1
change in x-values = 1
slope = 1/1 or 1
to find the y-intercept ('b'), select an ordered pair: (1, 6)
use the slope-intercept formula and solve for 'b':
6 = 1(1) + b
6 = 1 + b
5 = b
slope = 1
y-intercept = 5
Answer: -3.125
Step-by-step explanation: -1 divided by 8 = .125
Answer: 9
Step-by-step explanation:
4x²-7x+7 f(2)=4*(2)^2-7(2)+7=16-14+7=9
9.50 + (2.20)r
For example if he fixed 3 watches
9.50 + (2.20)3
We plug in 3 for r and he makes 6.60 extra.
