4.coordinate points are:

(-2,3)=(x1 , y1)

(1,y)=(x2 , y2)

slope =y2-y1/x2-x1

2=y-3/1-(-2)

2=y-3/1+2

2=y-3/3

do cross multiplication

2*3=y-3

6+3=y

9=y

3 no.

3(1-x)=-2(x-1)

3-3x=-2x+2

3-2=-2x+3x

1=x

4+y/3=2

4+y=3*2

4+y=6

y=6-4

y=2

kobusy [5.1K]

Answer:

He will finish the rest of the problems in 32.4 minutes.

Step-by-step explanation:

Since we are given that Yan has completed 3/5 of 45 problems i.e.

Since he complete each problem in minutes = $1\frac{4}{5} =\frac{9}{5} =1.8$

So, he completes 18 problems in minutes = 18 *1.8 = 32.4 minutes

Hence , He will finish the rest of the problems in 32.4 minutes.
