Bas_tet [7]

Answer:

c. 4y -x = 8

Step-by-step explanation:

Each of the equations can be put into slope-intercept form (solved for y) as follows:

a: y = 4x +9

b: y = 4x -8

c: y = (1/4)x +2

d: y = 4x -4

___

The equations containing the term "4x" all describe parallel lines. The equation containing (1/4)x describes a line that intersects the given line. It is not parallel to the others.

A survey asked students which vegetable they prefer. Of those who responded 17 said corn, 22 said carrots , 9 said green beans ,
