Set 1.6 Question 12 See attachment. [ATTACH=full]187[/ATTACH]
a) slope m3 is negative, so smalest one slope m1 >m2 so in increasing order, we have m3<m2<m1 b) b is y-intercept line y=m1x+b1 has negative value for b=>smalest one lines y=m2x+b2 and y=m3x+b3 have positive value for y-intercepts, and y-intercept of the y=m3x+b3 is greater value b1<b2<b3
you also see three equations, and they are helping you to determine what line has slope m1 and y-intercept b1 same apply for slope m2 and y-intercept b2, slope m3 and y-intercept b3 you also know what a slope means than compare all lines and determine slopes and y-intercept
