Which of the following is the equation of a line that passes through the point (1,4) and is parallel to the x-axis?

a. x=4

b. x=1

c. y=1

d. y=4

Option: D is the correct answer.

             D.   y=4

We know that any equation of a line that is parallel to x-axis is given by:

                                  y=a

and it passes through (0,a).

Hence, in the given question:

The equation of a line that passes through the point (1,4) and is parallel to the x-axis is:

                     D.  y=4

From the graph of y=4 we could observe that is satisfies the given condition.

step-by-step explanation:

the options are kind of confusing. i can tell you what i see going on here when i look at the graph.

the class and exam medians are closely related, and it looks like the low outlier on the exam did pull the median lower. [tex][/tex]

x = -3

y = -18

step-by-step explanation:

to solve by substitution, substitute one variable and solve for the other. then substitute again to find the remaining variable.

x-1/3(3x-9) = -3 since y=3x-9 substittute y.

x-1/3(3x-9)=-3

x + x +3 = -3

2x+3=-3

2x+3-3= -3-3

2x=-6

x=-3

substitute again into y=3x-9

y=3(-3)-9

y=-9-9

y=-18
