Find the Equation Using Two Points (5,6) , (2,6)

$(5, 6)$ , $(2, 6)$

Step 1

Use $y = m x + b$ to calculate the equation of the line, where $m$ represents the slope and $b$ represents the y-intercept.

To calculate the equation of the line, use the $y = m x + b$ format.

Step 2

Slope is equal to the change in $y$ over the change in $x$ , or rise over run.

$m = \frac{(change in y)}{(change in x)}$

Step 3

The change in $x$ is equal to the difference in x-coordinates (also called run), and the change in $y$ is equal to the difference in y-coordinates (also called rise).

$m = \frac{y_{2} - y_{1}}{x_{2} - x_{1}}$

Step 4

Substitute in the values of $x$ and $y$ into the equation to find the slope.

$m = \frac{6 - (6)}{2 - (5)}$

Step 5

Finding the slope $m$ .

Simplify the numerator.

Multiply $- 1$ by $6$ .

$m = \frac{6 - 6}{2 - (5)}$

Subtract $6$ from $6$ .

$m = \frac{0}{2 - (5)}$

Simplify the denominator.

Multiply $- 1$ by $5$ .

$m = \frac{0}{2 - 5}$

Subtract $5$ from $2$ .

$m = \frac{0}{- 3}$

Divide $0$ by $- 3$ .

$m = 0$

Step 6

Find the value of $b$ using the formula for the equation of a line.

Use the formula for the equation of a line to find $b$ .

$y = m x + b$

Substitute the value of $m$ into the equation.

$y = (0) \cdot x + b$

Substitute the value of $x$ into the equation.

$y = (0) \cdot (5) + b$

Substitute the value of $y$ into the equation.

$6 = (0) \cdot (5) + b$

Find the value of $b$ .

Rewrite the equation as $(0) \cdot (5) + b = 6$ .

$(0) \cdot (5) + b = 6$

Simplify $(0) \cdot (5) + b$ .

Multiply $0$ by $5$ .

$0 + b = 6$

Add $0$ and $b$ .

$b = 6$

Step 7

Now that the values of $m$ (slope) and $b$ (y-intercept) are known, substitute them into $y = m x + b$ to find the equation of the line.

$y = 6$
