to find the x int, sub in 0 for y and solve for x 5x + 9(0) = 0 5x = 0 x = 0
to find the y int, sub in 0 for x and solve for y 5(0) + 9y = 0 9y = 0 y = 0
the reason u cannot use just the intercepts is because the line goes through the origin (0,0)....The intercepts coincide giving u only 1 point...and that is not enough to graph a line
Your answer should be B 10m because 4x10=40 and that's the bxh then you need to divided by 2 do it would be 20. And 20m^2 is your answer so B is your answer
