I am stuck on this problem and I have a quiz with these problems tommorow! How do I solve 3x+4y=8 and x-2y=6 and graph it?
Ok first you solve for y (y=x format)
Divide by 4
now you know the slope is -3/4 and the y intercept is 2
How to graph: Knowing the y-intercept is 2, plot a point at (0,2) "x=0, y=2", and trace a point backwards from there using the slope until the x-axis is reached
Rise over run method
Now how to trace this starting from a single point y=2 and x=0, excuse my mouse writing:
Divide by -2
Here you know the y intercept is -3 and the slope (rise over run) is (1/2)
Use the same method to graph this starting at y=-3 and x=0
Here starting at (0,-3), you would trace up one point (positive 1), then over 2, then repeating again until you have enough points to plot a long line for the graph.
