Answer:
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:
