Question 331654: how do you graph negative two-thirds as the slope and negative 2 as the y-intercept i really need help on this PLEASE ANSWER THANK YOU !!!!!!

You can put this solution on YOUR website!
If -2 is the y-intercept, plot the point (0,-2). Then since the slope is -2/3, you are going to go down (because of the negative) 2 units (because of the 2 in the numerator) and then go right (you have already handled the negative) 3 units (because of the 3 in the denominator). Plot the point (3,-4).
Instead of plotting (3,-4), you actually could have gone up 2 for the 2 in the numerator and LEFT (for the minus sign) 3 for the denominator and plotted (-3,0).
Draw a line through the two points. Done.
The things to remember are: 1. If the slope is negative, then the line goes downward as you go from left to right. If the line goes up from left to right, then the slope is positive.
2. If the slope is 1 or -1 then the line makes a 45 degree angle with the x-axis. If the absolute value of the slope is greater than 1, the line is steeper than that, less than 1, then it is a smaller angle to the x-axis.
