What is the equation of the line parallel to the line y = 4 and passing through the point (2, -1)?

y = - 1

Step-by-step explanation:

y = 4 is the equation of a horizontal line parallel to the x- axis.

A line parallel must therefore be a horizontal line with equation

y = c

where c is the value of the y- coordinates the line passes through.

The line passes through (2, - 1) with y- coordinate - 1, thus

y = - 1 ← equation of parallel line

3x^3-x^2+6x-9

-7/8

step-by-step explanation:

instead of subtracting you add the -6/8 and -1/8
