Question

the graph of y=ax+b is a straight line which intersects the X axis at exactly one point namely ​

Answer 1

Given :

An equation of a straight line y = ax + b

To Find:

The point of intersection of the line with the x axis.

Solution:

We have the line y = ax  + b.

We can find the x intercept in different ways.

    (1) Equation for x axis is y = 0

• 0 = ax + b
• x = -b/a
• The point is ( -b/a,0)

    (2) Another way is to write it in intercept form

• y  =ax + b
• y/b  +  -ax/b = 1
• Here y intercept is b and x intercept is -b/a

The line y = ax + b intersects x axis at exactly one point namely (-b/a,0)

Answer 2

Answer:

the answer of these question is straight line
