What is the equation of a line that is parallel to the x-axis and passes through the point (2,-1)

y = - 1

Step-by-step explanation:

the equation of a line parallel to the x-axis has equation

y = c

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

the line passes through the point (2, - 1) with c = - 1

y = - 1 ← is the equation of the horizontal line

so far i think you have the right thing going for you just remember soh cah toh

step-by-step explanation:

sine over hypotenuse

cosine   equals adjacent

tangent over hypotenuse
