For each of the following, find the x-intercept and y-intercept and graph. i don't know how to find the x and y intercept because i don't know what to plug in to the equation. someone explain it to me!

X-intercept is where graph crosses x-axis. y-value is zero

2x - 4y=6

x-intercept (y=0)
2x - 4*0 = 6
2x=6  /:2
x=3

y-intercept (x=0)
2*0 - 4y=6
-4y=6 /:-4
y=-3/2

  for 2x-4y=6 x-intercept is 3, y-intercept is -3/2

-3x - 2y = 6
x-intercept is x=6/-3 = -2
y-intercept is y=6/-2 = -3

3x +4y = 12
x-intercept is x=12/3 = 4
y-intercept is y=12/4 = 3
