start with 6x - 4y = 24

add 4y to both sides of the equation and subtract 24 from both sides of the equation to get 6x - 24 = 4y

divide both sides of the equation by 4 to get 6/4 * x - 24/4 = y

flip sides and simplify to get y = 3/2 * x - 6

the equation is now in slope intercept form.

the slope is 3/2.

the y-intercept is -6.

since the y-intercept is the value of y when x = 0, then the coordinate point of the y-intercept is (0,-6).

the x-intercept is the value of x when y = 0.
to find that, set y = 0 to get 0 = 3/2 * x - 6.
add 6 to both dies and multiply both sides by 2/3 to get 6 * 2/3 = 3/2 * 2/3 * x.
simplify to get 12/3 = x
simplify further to get 4 = x.

the x-intercept is x = 4.
the coordinate point of the x-intercept is (4,0).

here's what the graph looks like.
