how though?

the line is going past (0,0) so there is no y-intercept. the y-axis is going up by a scale of 10 per 2 lines, or just 5 per line. the x-axis is going by 2 per 2 lines, or 1 per line. So to find the slope you have to do rise over run. Pick two points on the line and check how far they are using rise over run. So pick two points on the line so I can show you...
