-2y = 5x
Divide -2 from both sides.
y = -2.5x
You have to get y alone on one side so you have to get rid of everything else.5x - 2y = 10 2y = 5x - 10 y = 2.5x - 5......which is the equation in slope intercept form.
If: 5x+2y = 9 Then: y = -2.5x+4.5 in slope intercept form
5x+2y = 30 2y = -5x+30 y = -2.5x+15 Therfore the slope is 2.5 and y the intercept is 15.
5x+2y=-4 Subtract 5x from both sides 2y=-5x-4 divide by two on both sides y=-5/2x-2 y = -2.5x -2 in slope-intercept form
5x 2y = 10
(3, 2)
5x - 2y = 05x - 5x - 2y = 0 - 5x-2y = - 5x(-2y)/-2 = (-5x)/-2y = (5/2)x where the slope is 5/2 and the y-intercept is 0.
5x-2y=-3 -2y=-5x-3 y=(5/2)x+3/2 slope is 5/2
5x-2y=11 -2y=-5x+11 y=(5/2)x - 11/2 Slope is 5/2
Put in point slope/function form. 5X + 2Y + 3 = 0 5X + 2Y = - 3 2Y = - 5X - 3 Y = - 5/2X - 3/2 slope = - 5/2 ---------------- Y intercept = - 3/2 -------------------------
It is: y = -2.5x-2
If: 3x+2y = 5x+2y = 7 Then: 3x+2y = 7 and 5x+2y = 7 Subtract the 1st equation from the 2nd equation: 2x = 0 or x = o By substitution: x = 0 and y = 3.5
