#"see explanation"#

Explanation:

#"the intercepts are the coordinates of the points on the "#
#"x and y axes that the line passes through"#

#"we can use them to sketch the graph for a given equation"#

#"when the line crosses the y-axis the x-coordinate is zero"#

#"when the line crosses the x-axis the y-coordinate is zero"#

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

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

#x=0toy=0-3rArry=-3larrcolor(red)" y-intercept"#

#y=0to3x-3=0rArrx=1larrcolor(red)" x-intercept"#

#"plot "(0,-3),(1,0)" and draw a straight "#
#"line through them"#
