Find the Equation Using Slope-Intercept Form (0,1),4/5

$(0, 1), \frac{4}{5}$

Step 1

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.

$y = (\frac{4}{5}) x + b$

Substitute the value of $x$ into the equation.

$y = (\frac{4}{5}) \cdot (0) + b$

Substitute the value of $y$ into the equation.

$1 = (\frac{4}{5}) \cdot (0) + b$

Find the value of $b$ .

Rewrite the equation as $\frac{4}{5} \cdot 0 + b = 1$ .

$\frac{4}{5} \cdot 0 + b = 1$

Simplify $\frac{4}{5} \cdot 0 + b$ .

Multiply $\frac{4}{5}$ by $0$ .

$0 + b = 1$

Add $0$ and $b$ .

$b = 1$

Step 2

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.

$y = \frac{4}{5} x + 1$
