Answer:
D) b = 3, m = -2/3
Step-by-step explanation:
1. The y-intercept, b, is the coordinate where a line intersects with the y-axis.
- As you can see from the graph, the line intersects the y-axis at (0, 3), so the y-intercept, or b, is 3.
2. Given the information above, we can easily cross of A and C because they don't have their y-intercept as 3.
3. Now, since this line is going downward (or you can say it's a negative line), it's obviously going to have a slope that's negative.
- Since D is the only answer choice with a y-intercept of 3 and a slope of -2/3, D) is the correct answer.
Answer: I think Yes.

Answer:
They complete the hill in 8 hours
Step-by-step explanation:
We will need to solve these equations with a system of equations, so we need to isolate one variable in one of the equations and then replace it with another equation. After this, this means that Beatrice alone would construct the hill in 24 hours and Charlie 40. So, after finding the value A we will need to add A with B and C. This would get us 
. We will then divide 
. This will leave with 8h.
A= 7/120h
C=1/40h
B= 1/24h
His next step would be to c<span>onstruct the angle bisector of ∠A.</span>
