"see explanation"

Explanation:

"to find the intercepts"

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

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

x=0toy=0+7toy=7larrcolor(red)" y-intercept"

y=0to3x+7=0tox=-7/3larrcolor(red)" x-intercept"

"plot the points " (0,7),(-7/3,0)" and draw a straight line"
"through them"
graph{3x+7 [-20, 20, -10, 10]}
