Explanation:

"one way is to find the points where the graph crosses the"one way is to find the points where the graph crosses the
"x and y axes called the intercepts"x and y axes called the intercepts

• " let x = 0, in the equation for y-intercept" let x = 0, in the equation for y-intercept

• " let y = 0, in the equation for y-intercept" let y = 0, in the equation for y-intercept

x=0to0+y=-2rArry=-2x=00+y=2y=2

y=0tox+0=-2rArrx=-2y=0x+0=2x=2

"plot the points "(0,-2),(-2,0)plot the points (0,2),(2,0)
"and draw a straight line through them"and draw a straight line through them
