Question

Choose the equation of the line passing through the point (-3, 1) and parallel to y = -x - 4.

Answer 1

i got y=x+2

Answer 3

Your equation is going to be in y = mx + b form. The point gives us x and y, and the equation gives us m (parallel lines have the same slope, in this case -1). Let's plug in those values and solve for b!

y = mx + b
1 = (-1)(-3) + b
1 = 3 + b
b = -2

This means your general equation is y = -x-2

Answer 5

Sure

Answer 6

The tables below show the values of y corresponding to different values of x:

Table A
x 3 2 1
y 1 0 0

Table B
x 3 5 4
y -2 1 1


Which statement is true for the tables?

Both Table A and Table B represent functions.

Both Table A and Table B do not represent functions.

Table A does not represent a function, but Table B represents a function.

Table A represents a function, but Table B does not represent a function.

Answer 7

I got D

Answer 8

A function refers to a graph where every x-value has exactly 1 y-value. This means different x-values could have the same y-value, as long as there is just one (like what you get in a parabola). This means A is the correct answer.
