Question

1. 2x + 3y = -3
Which of the following states the x-intercept and the y-intercept of the equation above?


a. x-intercept = (-1 1/2, 0)
y-intercept = (0, -1)


b. x-intercept = (0, -2/3)
y-intercept = (-1, 0)


c. x-intercept = (5, 0)
y-intercept = (0, 6)


d. x-intercept = (0, -1 1/2)
y-intercept = (-1, 0)

Answer 1

to find the x-intercept.. replace y=0 and solve for x
to find the y-intercept.. replace x=0 and solve for y

for y=0 2x=-3
x=-3/2 = -(1 1/2)

so x intercept is (-1 1/2, 0)

for x=0 3y=-3
y=-1

so y intercept is (0, -1)
