Paha777 [63]

Answer:

y\le\dfrac{1}{2}x+2

Step-by-step explanation:

On a coordinate plane, a solid straight line has a positive slope and goes through (negative 4, 0) and (0, 2). This line has the equation

y-0=\dfrac{2-0}{0-(-4)}(x-(-4))\\ \\y=\dfrac{1}{2}(x+4)\\ \\y=\dfrac{1}{2}x+2

The origin belongs to the shaded region, so its coordinates must satisfy the inequality. Since

\dfrac{1}{2}\cdot 0+2=2\ge 0,

then the correct inequality is

y\le\dfrac{1}{2}x+2

wlad13 [49]

Answer:

Step-by-step explanation:

Given that:

Amount earned for 0 mile = $50 (earned for signing up)

Amount earned for walking 1 mile = $60 ($50 for signing up and $10 for. Walking)
