m = -2 and c = -8.

Therefore the y intercept is = -8.

Can the square of an integer be a negative number

Answers

If you square an integer, there is no way to get a negative as a result.

Let's look at -5².

-5² means -5 × -5 or 25.

So, there is no way to end up with a negative.
no it can't
minus on minus gives plus

E. 9x² + 42x + 49
Can anyone explain how to make it step by step?

Answers

When u see square that means u have to multiply the number by it self.
( 3x + 7 ) * ( 3x + 7 )
3x * 3x = 9x^2
3x * 7 = 21x
7 * 3x = 21x
7 * 7= 49
Now u have 9x^2 + 21x + 21x + 49 
Now u have to combine like terms meaning u have to add the number that have the same variable ( x )
21x + 21x= 42x 
Answer: E.)  9x^2 + 42x + 49
