Question

which gragh represents this equation 3x+7y=42

Answer 1

is there an illustration?

Answer 2

yea here it is lol and thanks for trying to help

Answer 3

If we find out where this equation, 3x+7y=42, crosses the y-axis and the x-axis, we can figure out which of the 4 graphs.

Where does it cross the x-axis at? If we are crossing the x-axis on the line, then that means that y=0.
3x+7y=42
3x+7(0)=42 [plug in 0 for y]
3x+ 0 =42 [divide both sides by 3]
x=14
the point (14,0) is on the line function of 3x+7y=42.

Do any of the graphs have a line that goes through the point (14,0) ?
