Chapter 4: Q14. (page 244)

Write an equation in point-slope form for the line that passes through each point with the given slope.
$(8, 3), m = - 2$

Short Answer

Expert verified

The equation of the straight line for the given condition is $y = - 2 x + 19$ .

Step by step solution

Step 1. State the concept of a straight line.

The standard form of slope and intercept form of the straight line is $y = m x + c$ .

Here, $m$ is the slope of the straight line and $c$ is the $y$ -intercept of the equation.

Step 2. State the equation of a line slope-point form.

The standard form of slope and point form of the straight line is $y - y_{1} = m (x - x_{1})$

Here $m$ is the slope of the straight line and is the point from which the straight line passes.

$(x_{1}, y_{1}) = (8, 3) m = - 2$

Step 3. Substitute the values to get the required equation.

Substitute the above values in the equation $y - y_{1} = m (x - x_{1})$

$y - y_{1} = m (x - x_{1}) y - 3 = - 2 (x - 8) y - 3 = - 2 x + 16 y = - 2 x + 19$

The equation of the straight line is $y = - 2 x + 19$ .
