Question 257483: I did this linear equation problem, but I want to make sure it is right.
Graph a line using the "friendly numbers" -2, -1, 0, 1, 2
1. y = 2x + 3 This is the answer I put down:
x / 2x+3 / y / (x,y)
-2 / 2(-2)+3 / -1 / (-2,-1)
-1 / 2(-1)+3 / 1 / (-1,1)
0 / 2(0)+3 / 3 / (0,3)
1 / 2(1)+3 / 5 / (1,5)
2 / 2(2)+3 / 7 / (2,7)
I didn't know how to make columns on the computer for my answers. The
above should be in columns, but I put slashes to indicate the columns. Now I am thinking about the answer because it states to a graph a line using the friendly numbers. Are my columns enough or do I have to graph a line?
