Question

Sketch the graph of the equation -4x+5y=20

Answer 1

-4x + 5y =20

First, we need to first find the points

To do that, simply find the x and y-intercepts

To find the y-intercept, substitute x =0 and solve for y

-4(0) + 5y = 20

5y =20

Divide both-side by 5

y = 4

We have (0,4) as a point

Next, find the x-intercept

-4x + 5(0) = 20

-4x = 20

Divide both-side by -4

x = -5

The other point is (-5, 0)
