Question

Write the following inequality in slope-intercept form.
9x + y < 4
Write your answer with y first, followed by an inequality symbol. Use integers, proper
fractions, and improper fractions in simplest form.

Answer 1

Answer:   y < -9x+4

Explanation:

Subtract 9x from both sides to get y < 4-9x and that's the same as y < -9x+4

The inequality sign stays the same. The answer in bold is of the form y < mx+b where m = -9 is the slope and b = 4 is the y intercept. The boundary is y = -9x+4 and this boundary is a dashed line. Shade below the dashed boundary to graph y < -9x+4.
