QUESTION:
what are the x- and y- intercepts for each equation
1. 5x-13y=20 2. 3x+8y=-24 3. x-4y=4
-------------------------------------------------------------------------------
ANSWER:
An x intercept is a point on the graph where y is zero
An y intercept is a point on the graph where x is zero.
For calculation,
X intercept, put y = 0 and
Y intercept, put x = 0
1. 5x-13y=20
For x intercept, Put y =0
==> 5x -13*0 = 20
==> 5x = 20
==> x = 20/5 = 4
For y intercept, put x = 0 in the given equation,
==> 5*0 -13y = 20
==> -13 y = 20
==> y = 20/ -13
2. 3x+8y= -24
x intercept,
==> 3x + 8*0 = -24
==> 3x = -24
==> x = -24 / 3
==> x = -8
Y intercept,
==> 3*0+ 8y = -24
==> 8y = -24
==> y = -24/8
==> y = -3
3. x - 4y = 4
X intercept,
==> x - 4*0 =4
==> x = 4
Y intercept,
==> 0 - 4y = 4
==> -4 y = 4
==> y = 4 / -4
==> y = -1
Hope you understood.
Regards.
