find the angle made by straight line x - 1 is equal to zero with the x axis and find its intercept on the x axis
Answers
Answer:
x-1=0 can be written as x=1. Hence for every value of y, the value of x is 1.
The intercept point is (1,0)
Now, the angle ~ clearly it's making 90° as per your question. Clearly, the equation x-1=0 is parallel to x=0 (which is the equation of the Y axis line). And we know X and Y axes intercept each other at 90°.
Basically, we express a linear expression as -> ax+by+c=0
In here, 1.x + 0.y +(-1) = 0
So we clearly see that any value of y won't affect the result as zero multiplied by something is always zero. Hence, we will always get x=1.
Now, determination of intercept on X-axis. In here, remember: the linear equation of X-axis is y=0 (or, a.x + b.0 + c = 0). Why? Cuz for every value of X on the X - axis line, the value of Y is zero!
Hence whenever you want to find intercept at X axis, make y=0 in the given equation. And to find intercept at Y axis make x=0.
