Question 160761: Could anyone please help with these? Find the slope and y-intercept for the given linear inequalities and graph them. 1. 3x-y>-4 m=____ b= ____ 2. x<-2 m= ___ b=____ .I am not sure how these are done.

You can put this solution on YOUR website!
The first thng to do is put the equation into slope/intercept form.
That form is given by y+=+mx+%2B+b where m is the slope and b is the intercept.
So, given 3x-y%3E-4
-y+%3E+-3x+-+4
+y+%3C+3x+%2B+4 remember to change the sign of the inequality when multipling or dividing by a negative number.
So the slope is 3 and the intercept is at the point (0,4)
To plot the inequality, draw the line. Use a dashed line since the inequality doesn't included an "equal to" part. Now shade in the area "less than" (below) the dashed line.
2) in this equation, you are given a linear equation with no y term in it. This line is a vertical line that goes through the point (2,0). The slope of a vertical line is 'undefined'. Again, the inequality is 'strict' (ther eis no equal to part. So use a dahed vertical line that goes through the point (2,0). Then shade in the area that is less than (to the left of) the line.
I hope this helps
