help with math graph 35 points

Because the equation is in slope-intercept form, we know the first point will be -4, as that is the y-intercept.
We can input a value of x into the equation to find the y value that goes along with that value of x.
y = (-5/6)x - 4
We'll use x = 6 for this.
y = (-5/6)6 - 4
y = -5 - 4
y = -9
to draw the graph we only require 2 points
choose any value of x, substitute into the equation and solve for y
x = 0 : y = 0 - 4 = - 4 ⇒ (0, - 4 )
x = 6 : y = - 5 - 4 = - 9 ⇒ (- 6, - 9 )
Plot these 2 points and draw a straight line through them for graph
