Explanation:

#"one way is to find the intercepts, where the graph crosses"#
#"the x and y axes"#

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

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

#x=0to0+y=-4rArry=-4larrcolor(red)" y-intercept"#

#y=0tox+0=-4rArrx=-4larrcolor(red)" x-intercept"#

#"plot these 2 points and draw a straight line through them"#
