Question

Find the x- and y-intercepts of the graph of x+10y=20

Answer 1

Explanation:

or, x+10y=20

or, y=10/20

or, y=1/2

or, y=2

therefore, y is equal to 2.

or, x=20-2

or, x=19

therefore, x is equal to 19

x+10y=20

So, x= 19

10y=2

19+2=20

Answer 2

x-intercept (20, 0). y-intercept (0, 2)

Explanation:

x-intercept when graph crosses x-axis (that is when y = 0).

so x + 10y = 20, x + 10(0) =20, x= 20. coordinate is (20, 0).

y-intercept when graph crosses y-axis (that is when x = 0).

so x + 10y = 20, (0) + 10y =20, y= 20/10 = 2. coordinate is (0, 2).
