I think that the 2 or 4 one are right. This one is hard for me too but just hope that you get right and hope that it is right.
Answer:
5: 45 miles
6: y=20x
Step-by-step explanation:
Cory . . . . 21/60 = 0.35 = 35 percent
Krista . . . 18/45 = 0.4 = 40 percent
Paula . . . 17/50 = 0.34 = 34 percent
From this point, I'm pretty sure you can line them up.
answer: y = 1.5x - 5.5
explanation:
use y = mx +b to model your equation
(m = slope, b = y-intercept)
let's start by finding slope
to find slope, subtract the y values over the x values.
- 4 - (-1) / - 5 - (-3)
solve and simplify.
-3 / -2
two negatives equals a positive, so convert into a decimal and remove the negative
you get 1.5.
now, plug the slope a y and x value into the equation to find b, the missing value.
-1 = 1.5(3) + b
-1 = 4.5 + b
-5.5= b
so, your equation is y = 1.5x - 5.5.
