Answer:

Step-by-step explanation:
<u>Straight line graphs</u>
- If the <u>y-values increase</u> as the <u>x-values increase</u>, the slope will be <u>positive</u>.
- If the <u>y-values decrease</u> as the <u>x-values increase</u>, the slope will be <u>negative</u>.
- If the line is <u>horizontal</u>, where each value of x has the same value of y, the slope will be <u>zero</u>.
Therefore, from inspection of the graph, the y-values increase as the x-values increase, so the slope is <u>positive</u>.
From the given answer options, the slope could be:

I'm not really sure, but I think the answer is D
Answer:
Step-by-step explanation:
Let's get the equation's and slope.
The photographer A y intercept is 25, so we know the hourly rate is 25 as well. We get
y = 25x + 25 as the equation.
y = 15x + 50 is the equation for B.
The answer should be something along the lines of Photographer a charges 10 more dollars hourly rate. Or Photographer B has 25 dollars more of a stand up rate.

Answer:
y = 3
Step-by-step explanation:
Subtract 11 from both sides to get:
2y = 6
Then divide both sides by 2 to isolate y:
y = 3
