Question

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

Answer 1

y intercept is when x = 0

So plug in for x in y= -2x - 3

You get y = -2(0) - 3 = -3

So when x = 0, y = -3 that is (0,-3)

Similarly, x intercept is when y = 0

So again, plug in 0 for y to get

0 = -2x - 3 so that 2x = -3

and x = -3/2

Thus, you have (-3/2 , 0) as the second coordinate

Answer 2

is that the answer . sorry im just a little confused.

Answer 3

(0,-3) and (-3/2,0)

Answer 4

thank u soo much :D

Answer 5

No problem!
