Answer:

y = 3 | x + 2 | - 5

Step-by-step explanation:

The absolute value function is:

y = | x |

Step 1. Function is vertically stretched by a factor of 3:

y = 3 * | x |

Step 2. Shifted two units left:

y = 3 | x + 2 |

Step 3. Shifted 5 units down:

y = 3 | x + 2 | - 5

Write an equation in standard form for a line that passes through (2,2) and (0,-3).

asambeis [7]

So,

The standard form is:
y = mx + b

First, we find "m," the slope. Subtract the y-coordinates from each other. Do likewise with the x-coordinates.

2 - -3 = 5
2 - 0 = 2

Slope = 5/2

$y= \frac{5}{2} x+b$

Now, we can substitute the second solution into this equation for x and y and solve for "b."

$-3= \frac{5}{2} *0+b$

$-3= b$

Now we have our complete equation.

$y= \frac{5}{2} x-3$
