Chapter 13: Q31. (page 534)

A line intersects the x- axis at a 45掳 angle.

What is its stope?

Short Answer

Expert verified

We showed thattan鈭�A=slopeofAC炉 .

Step by step solution

01

Step-1 – Given

Given that a line intersects the x-axis at a45鈭� angle.

02

Step-2 – To determine

We have to find the slope of the line.

03

Step-3 – Calculation 

We know that, the slope of a line is defined as 鈥渢he tangent of the angle which the line makes with positive direction of thex鈭�axisin the anticlockwise direction鈥�.

So,slope=tan胃=tan45掳=1.

Hence, the slope of line is 1.
