Answer:
r=1
Step-by-step explanation:
If you sub r for 1 you'll get 77 as the solution
7 cars full and 5 people on the next car
Answer: 1
Step-by-step explanation:
Minus the first equation with the second
x = -1
So y = 0
So there is only one solution
Answer: -0.6 or -3/5.
Step-by-step explanation: m = 6 / -10 = 3 / -5 = -0.6
Answer:
y - 7 = m (x- 0)
Step-by-step explanation:
Slope intercept form is y = mx + b. B is the y intercept, which gives us a point: (0, 7) that we can use in point slope form. M is the slope, 4/5. Now we have all the pieces for point slope form:
y - y1 = m (x - x1)
Now plug in the info!
y - 7 = m (x- 0)
