Answer:
Slope = 0.1 or 1/10
Y-int. = 15
Step-by-step explanation:
We have points (0,15), (3,45), (6,75), and (9,105).
slope is rise over run, or rise/run.
So, 9-3/105-45=6/60
now, simplify 6/60.
6/60=1/10 or 0.1
We already have the y-intercept, (0,15), because that's what intercepts the y-axis.
Since 10 millimeters is equal to 1 centimeter, all you have to do is divide 500 by 10. So, 500 divided by 10 is equal to 50. The final answer is 50 centimeters.

6r + 10
Explanation:
2(5 + 3r)
= (2)(5 + 3r)
= (2)(5) + (2)(3r)
= 10 + 6r
= 6r + 10
C=7
Because it's a right angle in total we know the 2 expressions combined will equal 90.
(8c-5)+(6c-3)=90
