Question

Choose the correct procedure used to graph the equation 3x + 9y = -18 using the intercepts method.

Answer 1

intercepts method so find the x and y intercept

x -intercept

let y= 0

3x + 9(0) = -18
3x = -18
x = -18/3
x = -6

y-intercept

let x = 0

3(0) + 9y = -18
9y = -18
y = -18/9
y = -2

therefore x-intercept is (-6,0)

y-intercept is (0,-2)

plot it and connect the dots

Answer 2

0+9y = -18
y=-2 x=0
3x=-18
x=-6 y=0
