Question 486960
Yes it can be. Here's the graph:
.
{{{graph(300,300, -5,3, -7, 4, x-2)}}}
.
This graph shows that the ordered pairs (-1,-3)and (-4,-6) are on the line and the slope is 1 because for every unit the graph moves horizontally to the right it also moves up one unit in the vertical direction.
.
Good job!!!
