8 because 7 is closer to 5 so you round up
According to (-b/a)
So --9/3=3
(-b/a) is the equation of the slope
Answer:
Step-by-step explanation:
The third graph
Answer:
Step-by-step explanation:
The given expression is

We will rewrite the expression

When we add the fraction
=
= 8
While Andre says the answer is 
because Andre added the denominator where he has to make a common denominator that should be 4 instead of 8.
Andre made mistake in this step
Picture is given below :
Given:
A line passes through the points (-6, 8) and (-16, 33).
To find:
The slope of the line.
Solution:
If a line passes through two points, then the slope of the line is

The line passes through the points (-6, 8) and (-16, 33). Using the above formula, the slope of the line is




Therefore, the slope of the line is -2.5.
