Question

I am trying to graph an equation. the equation is -2x+5y=20

Answer 1

Ok so lets rearrange this equation. It can be rewritten as:
y = 2/5x+4

Next, we know that a line is determined by two points. Thus, if we find the x and y intercept of this line, we can draw a line through these points. The x intercept in this case is -10,0 and the y intercept is 0,4. Draw a line through these two points and you have your line.

Answer 2

you just need 2 point and connect it as a line
let x=0 then 5y=20,y=4 that is (0,4)
let y=0 x=-10 that is (-10,0)
connect (-10,0) and (0,4) is your line

Answer 3

just use the intercepts

let y = 0 and solve for x.. this will be the x-intercept

-2x = 20 x = -10

let x = 0 to find the y=intercept

5y = 20 y = 4

plot the points (-10, 0) and ( 0 , 4) and then draw a line through both points

Answer 4

Thank you very much.
