    You can give any arbitrary number to "x" and solve for "y", for at least two points on the graph, if you join the points you'll obtain the graph of that line.

    I can use -5 for x right? But how would i go about solving y.. Thank you btw I'm sorry im so confused haha

    Say for instance, We consider x=-5, then: \[-5(-5)+y=-3\] Now, we just operate: \[25+y=-3\] \[y=-28\] So, therefore, the point "w", as we can call it, belongs in the line whose equation is given, if you represent this point on the cartesian plane, and repeat the process for another value of "x", then join the points, you'll obtain the graph of the line. \[w(-5,-28)\]

    -5x + y = -3

    another more direct approach let y be the subject

    Have you learned the form y = mx + b

    I added 5x to both sides :-)

    Would it be positive or negative?

    Yes it does, I have 2 answer choices that could work i just need to figure out if its negative or positive

    5x + (-5x) = 0

    The slope is positive because the 5 in 5x is positive.

    if u have something like this- ax+by=c then just divide all over by c \[\frac{ ax }{ c }+\frac{ by }{ c }=\frac{ c }{ c }\]\[\frac{ x }{ \frac{ c}{ a }}+ \frac{ y }{ \frac{ c }{ b } }=1\] calculate c/a and c/b and (c/a, 0)=point where the graph cuts x axis (0,c/b)=point where graph cuts y axis so basically just identify a,b,c and then find the points then join them and thats ur graph

    well thr best way was like what owl said u jst take some random value of x and get y and plot that point then u take another random value of x and put it in equation nd get y and pot this point and then join these 2 points
