Question

Find the intercepts and graph the equation x +5y =20

Answer 1

y-intercept: (0, 4)

x-intercept: (20, 0)

Step-by-step explanation:

y-intercept: The y-intercept of a graph is the point where the graph crosses the y -axis. That means, the point in which x = 0.

To find it, we can substitute x by 0 and find y.

x + 5y = 20

0 + 5y = 20

5y = 20

y = 20/5

y = 4

y-intercept: (0, 4)

x-intercept: The x-intercept of a graph is the point where the graph crosses the x-axis. That means the point in which y = 0.

To find it, we can substitute y by 0 and find x.

x + 5y = 20

x + 5*0 = 20

x = 20

x-intercept: (20, 0)

Finally, the graph of the equation is:
