Find equation of straight line passing through origin (1 0) and (2 1) ...
Equation of a straight line passing through two points
To find the equation of a straight line passing through two points, we first find the slope of the line using the formula:
\[ m = \frac{y_2 - y_1}{x_2 - x_1} \]
Given the points (1, 0) and (2, 1), the slope of the line is:
\[ m = \frac{1 - 0}{2 - 1} = 1 \]
So, the equation of the line passing through these two points is of the form \( y = mx \).
Equation of the line passing through origin
Since the line passes through the origin (0, 0), the equation of the line becomes:
\[ y = mx \]
Substituting the value of \( m = 1 \), we get:
\[ y = x \]
Intercept form of a straight line
The intercept form of a straight line is given by:
\[ \frac{x}{a} + \frac{y}{b} = 1 \]
Where 'a' is the x-intercept and 'b' is the y-intercept.
Finding x-intercept and y-intercept
For the line \( y = x \), the x-intercept occurs where y = 0 and the y-intercept occurs where x = 0.
X-intercept:
Setting y = 0 in the equation y = x, we get:
\[ 0 = x \]
So, the x-intercept is (0, 0).
Y-intercept:
Setting x = 0 in the equation y = x, we get:
\[ y = 0 \]
So, the y-intercept is (0, 0).
Therefore, the x-intercept and y-intercept of the line passing through the points (1, 0) and (2, 1) is (0, 0) and (0, 0) respectively.
