graph 5x-y+20=0

Question

please show how to graph 5x-y+20=0.

Answer 1

Given line 5x-y+20 = 0

subtract 5x and 20 from each side.

-y = -5x-20

Multiple to each side by negitive one.

y = 5x+20

If x = -1 then y = 15.

If x = 0 then y = 20.

If x = -2 then y = 10

Coordinate pairs are (0,20),(-1,15),(-2,10).

Graph

Draw the coordinate plane.

Plot the above pairs.

Connect the plotted points.

Then formed line indicating the line y =  5x +20.
