nd the slope of the line that passes through the given points. (2.4, 1.7) and (5.6, 2.3)

Lesson 2.1 Ex one. Is -2/3 a solution of the equation Yes this is a solution 3x+1=3+6x 2(-2/3) +1=3+6(-2/3) -6/3+1=3-12/3 -2+1=3-4 -1=-1 Ex two, is 1/3 a solution of the following equation No this is not a solution. 2a+5=a+6 2(1/3) +5= 1/3 +6 2/3 +5= 1/3 +6 2/3 +15/3= 1/3+6 17/3=19/3 Ex three, solve the equation for x X+5.2=-2.8 -5.2-5.2 X= 8 Ex four, solve the equation for y a. 5=1/4y b. Solve for a (4)5= (4) 1/4y 1/5a=-6 20= y (5) 1/5a= -6 (5) A= -30 Ex five, solve the equation for m 5m-4=9m+7-2m 5m-4=7m+7 5m-7m= 7+4 -2m=11 M= -11/2 or M=-5 1/2 Ex six, so
