1.-6 is the Y intercept

2.3/14

3.empty set

step by step explanation:

1.Y= mX-B

so B is -6

2.11-2raised3/14

2raised 3 is 8

that means 11-8/14=3/14

3. 7(x+3)= 7x-8

7x+21=7x-8

7x-7x=-8-21

0=-29

over here X is gone its so empty set

the image is given below

since the options are not given so we draw it from the equation

the given equation is

y = (x-1) (x+4)

y = y² + 3x - 4

the above equation is a quadratic equation which will have two roots. if we draw the graph for it, it will look like this
