A line parallel to the___ has no defined slope, and a line parallel to the has slope of zero. 1) X-axis. 2) x-axis
Y-axis
y-axis.

A line parallel to the y-axis has no defined slope, and a line parallel to the x-axis has slope of zero.

Step-by-step explanation:

Lines parallel to the y-axis are vertical and are undefined as they don't technically have a gradient.

lines parallel to the x-axis are horizontal and have a gradient of 0 since there is no positive or negative angle, it's just straight.

Hope this helped :)

step-by-step explanation:

because that's the answer

p ÷ r = tan(x)

step-by-step explanation:

given that there is a figure below shows a right triangle: a right triangle is shown with hypotenuse equal to q units and the length of the legs equal to p units and r units.

graph is missing so i will create the graph as per given information.

the angle between the legs having lengths p units and q units is y degrees. the angle between the legs having lengths r units and q units is x degrees.

now we need to find about what is p ÷ r equal to.

so we can use trigonometric ratio tan(x)=[altitude]/[base] to find the value of p ÷ r, because p is the altitude and r is the base.

p ÷ r=tan(x)

hence final answer is p ÷ r=tan(x).
