Are the lines 12x plus 3y-9 and -8x-2y14 parallel?
If you mean 12x+3y = -9 and -8x-2y = 14 then they are y = -4x-3 and y = -4x-7 respectively which means that they are parallel lines because they both have the same slope of -4 but with different y intercepts
How do you put 7x 2y14 in a graph?
Restate the question: How do you graph 7x+2y=14? The easiest way to graph this equation is to find the intercepts. . . To find the y-intercept, let x=0: 7(0)+2y=14 <=> 2y=14 <=> 2y/2=14/2 <=> y=7, so mark the point (0,7) on the graph. To find the x-intercept, let y=0: 7x+2(0)=14 <=> 7x=14 <=> x=2, so mark (2,0) on the graph and draw a straight line through the 2 points. With a little practice, and if the numbers are 'nice', you can almost do this by just looking at the equation, or you can think of (0,_),(_,0). My students call this "googly eyes"!
