Answer:
y=7/5x+7
Step-by-step explanation:
Use the saying "rise over run" to find the slope. If we go from the bottom most dot, we have to rise 7 and run 5 to reach the next dot, making the slope 7/5.
Next, we have to find the y-intercept. Do this by locating where the line crosses the y-axis, in this case it is at 7.
Finally, plug these numbers into slope-intercept format: y=mx+b (m is slope, and b is y-intercept).
Answer:
The answer is D
Step-by-step explanation:
Answer:
-3a^2 + 11a
Step-by-step explanation:
= 4a + -3a^2 + 7a
combine like terms
= -3a^2 + 11a
Subtract 650 by 450 and that is for the first top square
