Find the Equation Using Slope-Intercept Form m=1 , b=-1

$m = 1$ , $b = - 1$

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.

$y = (1) \cdot x + b$

Step 3

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

$y = (1) \cdot x - 1$

Step 4

Simplify the slope y-intercept form of the equation.

Remove parentheses.

$y = (1) \cdot x - 1$

Multiply $1$ by $x$ .

$y = 1 \cdot x - 1$

Remove parentheses.

$y = (1) \cdot x - 1$

Multiply $x$ by $1$ .

$y = x - 1$
