Answer:
Step-by-step explanation:
Thinking process:
The distributive property states that:
You can multiply a sum by multiplying each addend separately and then adding the products.
Let's look at the expression again:
−9(−2x − 3)
This is equals to =
The rule let's us distribute the -9 to both -2x and -3
This gives the two numbers:
=
Answer:
D.
Step-by-step explanation:
When a line is perpendicular to another, their slopes will be opposite reciprocal. For example, 1 would be -1, -3 would be , and
would be -5. The equation is written in slope-intercept form:
m is the slope, so find the equation with the opposite reciprocal of 3, :
is the only option with the correct slope, so the answer is D.
