Can someone PLEASE AND I MEAN PLEASEEE HELP ME plsss i put brainliest !! pleasee

Step-by-step explanation:

1) y  = 3x + 1

When x = -1 ,   y = 3*(-1) + 1              

                          = -3 + 1

                        y = -2

(-1 , -2)

When x = 0 ,  y = 3*0 + 1

                      y = 1

(0 , 1)

When x = +1 , y = 3*1 + 1

                          = 3 + 1

                       y = 4

(1 , 4 )

Plot these points in the graph and join the points.

2) y = 2x -1

When x = -1 ,         y = 2*(-1) - 1

                                = - 2 - 1

                             y = -3

(-1 , -3)

When x = 0,      y = 2*0 - 1

                        y = -1

(0 , -1)

When x = +1 , y = 2*1 -1

                         = 2 - 1

                       y = 1

(1 , 1)

f(x) = x^3 -2x^2 -3x

x( x^2 -2x-3)

x( x^2 +x -3x -3)

x( x(x+1) -3(x+1))

x( x-3)( x+1)

so zeroes are 0, 3,-1

its (2) option

- (2, -7)

- lines r and s and lines t and u must be parallel
