The x intercept is the point where y = 0, the y intercept is the point where x =0:
For the x intercept:
5x + 2y = 20, but y = 0
=> 5x + 0 = 20
=> x = 20/5 = 4.
So the x intercept is at (4, 0).
For the y intercept:
5x + 2y = 20, but x = 0
[The rest of the calculation is left as an exercise for the reader.]
y-intercept: 2 x-intercept: 4
4x+2y = 20 2y = -4x+20 y = -2x+10
x + 2y = 10At the x-intercept, y=0:x = 10At the y-intercept, x=0 ==> 2y = 10y = 5
4x + 2y = 20 2y = -4x + 20 y = -2x + 10.......but you may also write it as y = 10 - 2x.
3x+2y=20 5x-2y=1 (3x+2y) + (5x-2y)= 20+1 3x+5x= 21....... 8x=21.........x=2 5/8 Subsitute x=3(2 5/8)+ 2y=20........... 7 7/8 +2y=20.........2y= 20- 7 7/8....... y=6 1/16
y-intercept: 2 x-intercept: 4
4x+2y = 20 2y = -4x+20 y = -2x+10
x + 2y = 10At the x-intercept, y=0:x = 10At the y-intercept, x=0 ==> 2y = 10y = 5
4y = 2y + 40 4y - 2y = 2y -2y +40 2y = 40 y = 20 check 4(20) = 2(20) +40 80 = 80
4x + 2y = 20 2y = -4x + 20 y = -2x + 10.......but you may also write it as y = 10 - 2x.
3x+2y=20 5x-2y=1 (3x+2y) + (5x-2y)= 20+1 3x+5x= 21....... 8x=21.........x=2 5/8 Subsitute x=3(2 5/8)+ 2y=20........... 7 7/8 +2y=20.........2y= 20- 7 7/8....... y=6 1/16
63 + 20 - 60 = 23
If you mean: 5x-2y = 20 then the x and y intercepts are (4, 0) and (0, -10) respectively and when joined together on the Cartesian plane forms a straight line.
The x intercept would be 7/2 and y intercept would be 7/2.
x = -4 and y = 4
This means that 2y - 3 = 2y + 4 which is not possible.
y=16 x= -4
