Question 409472: please i need help!! gaph the line w/the givven point and slope (-2,5) -1
I understand that y=mx+b
5= -2(-1)+b
b=3 right??
so how do I graph a line like this?? so frustrated!!

Hi, Previously posted.

graph Line with slope m = -1, passing thru Pt(-2,5)

 y = mx + b   |Yes

 5 = -2(-1)+ b  |good work, using ordered pair Pt(-2,5) to solve for b

 3 = b        |Yes

 y = -x + 3  | y-intercept is Pt(0,3)

Note m = -1/1: 

as y increases/decreases by 1, x increases/decreases by 1 in opposite direction

Thus Pt( 1,2) and Pt(-1,4) on this line.  Plotting and connecting with a line:
