Aline is drawn through (-7, 11) and (8.-9). The equation y - 11 = 4(x + 7) is written to represent the line. Which
equations also represent the line? Check all that apply.
1. For parentheses:
Distribute
y-11 = *x-7)
y-11 = x
-4x+5
28
2. If necessary:
Combine Terms
3. Apply properties:
Add Subtract
3y = - 4x +40
4x + y = 21
4x + 3y = 5
4x + 3y = 17
Multiply
Divide
4. To start over:

b. 2 and 4

step-by-step explanation:

the answer is 13

step-by-step explanation:

5*5=25

12*12=144

25+144=169

169^2=13

the correct option is:

b. a value of the variable that makes the polynomial equal to zero.

the root or roots of a polynomial are the values of the variable that makes the polynomial equal to 0. we can find the roots of a polynomial making the expression equal to 0 and then, isolating the variable (it it has just one variable).

for example, given the following polynomial:

the root or zero of the polynomial, can be found by making the expression equal to 0, and then, isolating the variable, so, finding the root we have:

therefore, we have that the root of the polynomial is equal to 2.

we must remember that the number of roots that a polynomial can have, will depend on the degree of the polynomial, a first degree polynomial have will have one single root, a second degree polynomial (quadratic expression) may have two roots and so.

hence the correct option is:

b. a value of the variable that makes the polynomial equal to zero.

have a nice day!
