Question

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








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

Answer 1

For 17, you'll be plugging in various values of x to get corresponding values of y

if x = 0, then

y = -2x - 3
y = -2(0) - 3 ... replace x with 0, then evaluate
y = 0 - 3
y = -3

So we'll have this row

Answer 2

if x = 1, then

y = -2x - 3
y = -2(1) - 3 ... now replace x with 1, since x = 1
y = -2 - 3
y = -5

another pair is x = 1, y = -5
