Part 1) [tex]y=1.5x+5[/tex]  

Part 2) [tex]y=-(2/3)x-(11/3)[/tex]

Part 3) [tex]y=0.25x+2.75[/tex]    

Part 4) [tex]y=-2x+5[/tex]  

Part 5) [tex]y=0.5x-1[/tex]  

Part 6) The graph in the attached figure

Step-by-step explanation:

Part 1) we have

[tex]m=3/2=1.5[/tex]

[tex]point(-2,2)[/tex]

The equation of the line into point slope form is equal to

[tex]y-y1=m(x-x1)[/tex]

substitute

[tex]y-2=1.5(x+2)[/tex]

[tex]y=1.5x+3+2[/tex]

[tex]y=1.5x+5[/tex]

Part 2) we know that  

If two lines are perpendicular

then

the product of their slopes is equal to minus one

so

[tex]m1*m2=-1[/tex]

the slope of the line 1 is equal to

[tex]m1=1.5[/tex]

Find the slope m2

[tex]1.5*m2=-1[/tex]

[tex]m2=-2/3[/tex]

Find the equation of the line 2  

we have

[tex]m2=-2/3[/tex]

[tex]point(-7,1)[/tex]

The equation of the line into point slope form is equal to

[tex]y-y1=m(x-x1)[/tex]

substitute

[tex]y-1=(-2/3)(x+7)[/tex]

[tex]y=-(2/3)x-(14/3)+1[/tex]

[tex]y=-(2/3)x-(11/3)[/tex]

Part 3) we have

[tex]m=1/4=0.25[/tex]

[tex]point(1,3)[/tex]  

The equation of the line into point slope form is equal to

[tex]y-y1=m(x-x1)[/tex]

substitute

[tex]y-3=0.25(x-1)[/tex]

[tex]y=0.25x-0.25+3[/tex]

[tex]y=0.25x+2.75[/tex]

Part 4) we have

[tex]m=-2[/tex]

[tex]b=5[/tex] -----> y-intercept

we know that

The equation of the line into slope intercept form is equal to

[tex]y=mx+b[/tex]

substitute the values

[tex]y=-2x+5[/tex]

Part 5) we have that

The slope of the line 4 is equal to [tex]-2[/tex]

so

the slope of the line perpendicular to the line 4 is equal to

[tex]-2*m=-1\\m=(1/2)=0.5[/tex]

therefore

in this problem we have

[tex]m=0.5[/tex]

[tex]point(-2,-2)[/tex]

The equation of the line into point slope form is equal to

[tex]y-y1=m(x-x1)[/tex]

substitute

[tex]y+2=0.5(x+2)[/tex]

[tex]y=0.5x+1-2[/tex]

[tex]y=0.5x-1[/tex]
