I’m pretty sure this is right. if you add -3 and 7 you get 4 and if you multiply the two, you get -21. hope this helped!
Answer:
Step-by-step explanation:
FIRST multiply the coefficients together:
15a^2*b^7*a^3*b^8
Add up the exponents of the "a" terms:
15*a^(2 + 3), and, finally, add up the exponents of the "b" terms:
15*a^5*b^15
<h2>Answer:</h2>
The Slope is 
<h2>Explanation:</h2>
Notice that both the points, 
and 
, are on the line. So we can use those points to calculate the slope. Recall that that slope of the line 
can be calculated by 
if we have the points, 
and 
.
<h3>Calculating for the slope of the line:</h3>
Given:
