Question

17. Model the function rule y = -2x - 3 with a table of values.

Answer 1

take some values of x say -3, -2, -1 , 0 . 1. 2. 3
and find the corresponding values of y by substituting them in y = -2x - 3

Answer 2

okay so how do i find the corresponding values of y?

Answer 3

@cwrw238

Answer 4

substitute each x in the equation y = -2x -3

for ex y = -2(-3) - 3 simplify the right side and that will get you y
for when x = -3

Answer 5

@Jim766 okay :)

Answer 6

x y
-3 3
-2 1
-1 -1

you good

Answer 7

okay, do i do anything else?

Answer 8

depends how many values you need in the table...but no, that is it
you can find as many x's and y's as you want

Answer 9

okay thank you, could you help me with another question?

Answer 10

sure

Answer 11

For the function rule y = -2x - 3, provide the x-y coordinates of the y-intercept and the x-intercept.

Answer 12

the x intercept is where y = 0 (____, 0 )

to find this, substitute 0 in for y and solve for x ,

0 = -2x-3

the y intercept is where x = 0 ( 0 , ____)

y = 2(0) -3

Answer 13

thank you :)
