∙ 12y agomate, we would have two different points from the x intercept and the y intercept.
The first point would be (5,0), the second would be (0,-4), which we find from the intercepts.
thus now we can use the equation.
y-y1=y2-y1
x-x1 x2-x1 where you can substitute these two points into the equation
Hence:
y-0=-4
x-5 -5
which then equals,
-5y=-4(x-5) which we expand
-5y= -4x+20, now we move the -4x+20 to the otherside of the equation, effectively multiplying it by -1
thus, 4x-5y-20=0, and that is your equation for your question.
