Find the Equation Using Slope-Intercept Form m=3 , b=-3

$m = 3$ , $b = - 3$

Step 1

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

$y = m x + b$

Step 2

Replace the known value of $m$ in the slope y-intercept form of the equation.

$y = (3) \cdot x + b$

Step 3

Replace the known value of $b$ in the slope y-intercept form of the equation.

$y = (3) \cdot x - 3$

Step 4

Simplify the slope y-intercept form of the equation.

Remove parentheses.

$y = (3) \cdot x - 3$

Multiply $3$ by $x$ .

$y = 3 \cdot x - 3$

Remove parentheses.

$y = (3) \cdot x - 3$

Multiply $3$ by $x$ .

$y = 3 x - 3$
