Question

Graph solve for y 5y-x=20

Answer 1

Answer: y=1/5x+4 !!!

Rewrite in slope intercept form (y=mx+b) so:

5y=x+20

Divide by 5

5y/5=x/5+20/5

Then solve so you’ll get

Y=1/5x+4

Answer 2

$5y-x=20$            add x to both sides

$5y=x+20$          divide both sides by 5

$\boxed{y=\dfrac{1}{5}x+4}$

It's the equation of a line. We need only two points to the plot the graph.

Choice any two values of x. Put them to the equation of a line and calculate the values of y.

for x = 0:

$y=\dfrac{1}{5}(0)+4=0+4=4\to(0,\ 4)$

for x = 5:

$y=\dfrac{1}{5}(5)+4=1+4=5\to(5,\ 5)$
