Question

On a coordinate plane, a dashed straight line has a positive slope and goes through (negative 1, negative 1) and (0, 1). Everything to the left of the line is shaded. Which linear inequality is represented by the graph? y > 2x + 2 y ≥ One-halfx + 1 y > 2x + 1 y ≥ One-halfx + 2

Answer 1

Answer:

y > 2x + 1  

Step-by-step explanation:

The equation of a straight line is

y = mx + b

Your graph looks like the diagram below.

Calculate the slope of the line:

$\begin{array}{rcl}m & = & \dfrac{y_{2} - y_{1}}{x_{2} - x_{1}}\\\\ & = & \dfrac{1 - (-1) }{0 - (-1)}\\\\& = & \dfrac{2}{1}\\\\& = & \mathbf{2} \\\end{array}$

That eliminates Options B and D.

The y intercept is at y = 1.

That eliminates Option A.

The only inequality that fits is  

y > 2x + 1

Answer 2

Answer:

If it shows a table, the answer is b y$y\leq -2x+3$
