Question

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

Answer 1

for y-intercept, x coordinate is zero. so substitute x=0 and get y-intercept
y=-2(0)-3 = -3
so y-intercept is (0, -3)

for x-intercept, y coordinate is zero. so substitute y=0 and get x-intercept
0=-2x-3 => 2x = -3 => x = -3/2
so x-intercept is (-3/2, 0)

Answer 2

oooo thanks! i understand it now..so those are my answers right

Answer 3

Yes the last lines give the coordinates of y-intercept and x-intercept

Answer 4

ooh yeah thanks sooo much
