What is the equation in standard form?
+128407 We have the points (0, 15) and ( 150, 0 )
Slope = [ 0 - 15 ] / [ 150 - 0 ] = -15 / 150 = - 1 / 10
Equation using ( 0 , 15)
y = (-1/10) ( x - 0) + 15
y = (-1/10) x + 15 multiply through by -10
-10y = x - 150 add 10y to both sides
0 = x + 10y - 150
1x + 10y - 150 = 0 ⇒ Standard Form
