CPM Homework Help : CCA2 Problem C-7

Write the inequality represented by the graph below.
A dashed line going through (1, comma 0) and (0, comma 1). The graph is shaded above the line.

Hint 1:

Find the equation of the line, $y = mx + b$ .
$m =$ slope (growth) and $b = y$ -intercept.

Hint 2:

Draw a growth triangle and find the $y$ -intercept.

Step:

A slope triangle is drawn between the two points above.

Hint 3:

Is the shaded area above or below the line?
If the shaded area is above the line, the inequality is greater than the line.
If the shaded area is below the line, the inequality is less than the line.

Hint 4:

A less than $(<)$ or greater than $(>)$ sign is a dotted line,
while a less than or equal to $(≤)$ or greater than or equal to $(≥)$ sign is a solid line.

Answer:

$y > 2x - 1$
