    OK, so feed them x values into your formula to get the corresponding y values. Plot the pairs and join the dots........

    Y=-2x+3 this is short-hand. It means if you replace x with a number, you can figure out y for example, replace x with 0: y= -2*0+3 now do the arithmetic to find y

    You need to know order of operations: do multiplication first, then addition

    Best Answer - Chosen by Asker The general equation of a straight line graph is y = mx + c, where m is the slope and c the intercept on the y axis. So the slope is 2, and the y intercept is -3. To plot, calculate y when x = -3: y = 2x - 3 y = 2*(-3) - 3 y = -6 - 3 y = -9, so plot the point (-3, -9) Now find y when x = 3: y = 2*3 - 3 y = 6 - 3, y = 3, so plot the point (3,3) Join the two points you have plotted, and there is your graph.
