First, you must simplify the equation.
(-5y)=(-300)
[Divide by -5]
y=60
Now, the equation is as simple as it can be. Draw a horizontal line across y's 60. You are now finished!
X intercept: -5 Y intercept: +3
If: 4x = 5y Then: x = 5y/4
(-5, 2)
7
y = -6
35
X intercept: -5 Y intercept: +3
Simultaneous Equations. 4x + 5y = 51 4x - 5y = 21 eliminate 'y' by addition. Hence 8x = 72 x = 72/8 x = 9 When x = 9 Substitute into eith equation. 4(9) + 5y = 51 36 + 5y = 51 5y = 51 - 36 5y = 15 y = 3 Hence the answer is ( x,y) = ( 9,3).
5y=25x 25x=5y -5y 25x-5y=0
If: 4x = 5y Then: x = 5y/4
(-5, 2)
It's a non-standard form of the equation for a straight-line graph with a slope of 18 and a y-intercept of 16.
4x+5y = 7 5y = -4x+7 y = -4/5x+7/5 in slope intercept form So the slope of the perpendicular line is plus 5/4
If: 5y = 4735 Then: y = 947
7
5y + 7 = 25y = -5y = -1
y = -6
