Question

Which graph is the line y=-2/5x+3?

Answer 1

1st we should find the point where the line intersects with the axises 
put x= 0 , so y= 3 ---- > the 1st point (0,3) 
put y=0 , so x = 7.5 ----> the 2nd point (7.5,0) 
so it's the first graph on the left 

Answer 2

We can start off by using process of elimination. There are only 2 graphs (the first one and last on as appeared on my screen) that can be correct since the others do not have a y-intercept of 3. Then, we can go to the next step which is determining the slope of the remaining lines. The first graph has a slope of -2/5 while the last one has a slope of 5/2. As a result, the first graph, or the graph that has the line with smallest slope showing in quadrant 1 and 2, is the graph of the line y=-2/5x+3.
