How do you graph -5x+2y=105x+2y=10 using intercepts?

The intercepts are (-2, 0) and (0, 5)(2,0)and(0,5)

Explanation:

All points along the x-xaxis have their y- value =0.

All points along the y-yaxis have their x- value =0.

To find the yyintercept of a line,make x = 0.

To find the xxintercept of a line,make y = 0.

Once you have the x- and y-xandy intercepts, you have two points of the line.

Draw a line which passes through the two points.

-5color(red)(x) +2color(blue)(y) = 105x+2y=10

For x-xint, color(blue)(y=0)y=0

rarr -5x +2color(blue)((0)) = 105x+2(0)=10

-5x = 10" div -55x=10÷5

x = 10/(-5) = -2 " "x = -2 x=105=2 x=2

For y-yint, color(red)(x=0)x=0

rarr -5color(red)((0))x +2y = 105(0)x+2y=10

2y= 10" "div 22y=10 ÷2

y = 10/(2) = 5 " "y = 5y=102=5 y=5
