Write the equation of a line that passes through the point (-8,-10) and is parallel to the x-axis.

y=-10

Step-by-step explanation:

if the line is parallel to the x-axis, that means that the slope equals zero, so m=0, and the equation of a line is:

y=mx+b

so, we would have to plug into the equation what we know, so:

y=0x+b

now we need to find b to complete the equation, so plug in the (x,y) of the coordinate you were given into the equation as, x=-8 and y=-10:

-10=0(-8) +b

now, simplify to get b on its own:

-10= 0+b

-10=b

now that we know what b is, we can create the equation with what we know, m=0 and b=-10:

y=0x-10

but zero times any number is automatically zero, so:

y=-10
