Find the Slope and y-intercept q(x)=5x-(2+9x)/7

$q (x) = 5 x - \frac{(2 + 9 x)}{7}$

Step 1

Rewrite in slope-intercept form.

The slope-intercept form is $y = m x + b$ , where $m$ is the slope and $b$ is the y-intercept.

$y = m x + b$

Simplify the right side.

Simplify $5 x - \frac{2 + 9 x}{7}$ .

To write $5 x$ as a fraction with a common denominator, multiply by $\frac{7}{7}$ .

$y = 5 x \cdot \frac{7}{7} - \frac{2 + 9 x}{7}$

Simplify terms.

Combine $5 x$ and $\frac{7}{7}$ .

$y = \frac{5 x \cdot 7}{7} - \frac{2 + 9 x}{7}$

Combine the numerators over the common denominator.

$y = \frac{5 x \cdot 7 - (2 + 9 x)}{7}$

Simplify the numerator.

Multiply $7$ by $5$ .

$y = \frac{35 x - (2 + 9 x)}{7}$

Apply the distributive property.

$y = \frac{35 x - 1 \cdot 2 - (9 x)}{7}$

Multiply $- 1$ by $2$ .

$y = \frac{35 x - 2 - (9 x)}{7}$

Multiply $9$ by $- 1$ .

$y = \frac{35 x - 2 - 9 x}{7}$

Subtract $9 x$ from $35 x$ .

$y = \frac{26 x - 2}{7}$

Factor $2$ out of $26 x - 2$ .

Factor $2$ out of $26 x$ .

$y = \frac{2 (13 x) - 2}{7}$

Factor $2$ out of $- 2$ .

$y = \frac{2 (13 x) + 2 (- 1)}{7}$

Factor $2$ out of $2 (13 x) + 2 (- 1)$ .

$y = \frac{2 (13 x - 1)}{7}$

Write in $y = m x + b$ form.

Apply the distributive property.

$y = \frac{2 (13 x) + 2 \cdot - 1}{7}$

Multiply $13$ by $2$ .

$y = \frac{26 x + 2 \cdot - 1}{7}$

Multiply $2$ by $- 1$ .

$y = \frac{26 x - 2}{7}$

Split the fraction $\frac{26 x - 2}{7}$ into two fractions.

$y = \frac{26 x}{7} + \frac{- 2}{7}$

Move the negative in front of the fraction.

$y = \frac{26 x}{7} - \frac{2}{7}$

Reorder terms.

$y = \frac{26}{7} x - \frac{2}{7}$

Step 2

Use the slope-intercept form to find the slope and y-intercept.

Find the values of $m$ and $b$ using the form $y = m x + b$ .

$m = \frac{26}{7}$

$b = - \frac{2}{7}$

The slope of the line is the value of $m$ , and the y-intercept is the value of $b$ .

Slope: $\frac{26}{7}$

y-intercept: $(0, - \frac{2}{7})$

Slope: $\frac{26}{7}$

y-intercept: $(0, - \frac{2}{7})$

Step 3

Find the Slope and y-intercept q(x)=5x-(2+9x)/7
