Algebra Examples

m = 4

$m = 4$ ,

b = 7

$b = 7$

Step 1

Find the value of

b

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

y = m x + b

$y = m x + b$

Step 2

Replace the known value of

m

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

y = (4) \cdot x + b

$y = (4) \cdot x + b$

Step 3

Replace the known value of

b

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

y = (4) \cdot x + 7

$y = (4) \cdot x + 7$

Step 4

Simplify the slope y-intercept form of the equation.

Step 4.1

Remove parentheses.

y = (4) \cdot x + 7

$y = (4) \cdot x + 7$

Step 4.2

Multiply

4

$4$ by

x

$x$ .

y = 4 \cdot x + 7

$y = 4 \cdot x + 7$

Step 4.3

Remove parentheses.

y = (4) \cdot x + 7

$y = (4) \cdot x + 7$

Step 4.4

Multiply

4

$4$ by

x

$x$ .

y = 4 x + 7

$y = 4 x + 7$

y = 4 x + 7

$y = 4 x + 7$

Step 5

m = 4, b = 7

$m = 4, b = 7$
