Question

Which linear inequality is represented by the graph?

Answer 1

y > 2x + 1

Explanation:

Look at anyone point that intersects, let's choose (1, 3). From this point it rises 2 then run 1 to get to point (2, 5). Rise over run is your slope...

m =
`(2)/(1)` or simply 2

y-intercept is the point in which the line crosses the y line, in this case 1

Equation of line:

y = mx + b

m is the slope and b is the y-intercept. Use these to form the equation. Since the area above the line is shaded and the line is dotted, change the "=" to ">".

y > 2x + 1
