The slope intercept equation is 3y+ 2x = -4.5,
The equation of a straight line in the form y = mx + b where m is the slope of the line and b is its y-intercept.
let the two points from the graph is (4, -4) and (-2, 0)
then
m= 4/ -6= -2/3
and the intercept is 1.6 as the line intersects the y- axis.
So, the slope intercept is
y= -2/3x - 1.6
3y= -2x - 4.5
3y+ 2x = -4.5
