Graph 5x+2y<10

$5 x + 2 y < 10$

Step 1

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

Solve for $y$ .

Subtract $5 x$ from both sides of the inequality.

$2 y < 10 - 5 x$

Divide each term in $2 y < 10 - 5 x$ by $2$ and simplify.

Divide each term in $2 y < 10 - 5 x$ by $2$ .

$\frac{2 y}{2} < \frac{10}{2} + \frac{- 5 x}{2}$

Simplify the left side.

Cancel the common factor of $2$ .

Cancel the common factor.

$\frac{2 y}{2} < \frac{10}{2} + \frac{- 5 x}{2}$

Divide $y$ by $1$ .

$y < \frac{10}{2} + \frac{- 5 x}{2}$

Simplify the right side.

Simplify each term.

Divide $10$ by $2$ .

$y < 5 + \frac{- 5 x}{2}$

Move the negative in front of the fraction.

$y < 5 - \frac{5 x}{2}$

Rearrange terms.

$y < - \frac{5 x}{2} + 5$

Reorder terms.

$y < - (\frac{5}{2} x) + 5$

Remove parentheses.

$y < - \frac{5}{2} x + 5$

Step 2

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

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

$m = - \frac{5}{2}$

$b = 5$

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

Slope: $- \frac{5}{2}$

y-intercept: $(0, 5)$

Slope: $- \frac{5}{2}$

y-intercept: $(0, 5)$

Step 3

Graph a dashed line, then shade the area below the boundary line since $y$ is less than $- \frac{5}{2} x + 5$ .

$y < - \frac{5}{2} x + 5$
