Answer:

  A

Step-by-step explanation:

It is usually sufficient to look at one section of the graph to answer a question like this. Often the best choice is the section that has a solid dot at the end of the curve. Here, that is the right section.

The left end of the right section is at x=-2, so that part of the function is defined for x ≥ -2. The line to the right has a positive slope, so the coefficient of x will be positive.

Only one answer choice has a positive x-coefficient for x ≥ -2.

Answer:

Step-by-step explanation:

This graph is made up of two different, separate line segments.  In other words, it comes in two pieces which can be described as a pair of linear functions.

We call this a "piecewise linear" function.  Choice A is the best one.

Line K has a slope of -5. Line j is perpendicular to line k and passes through the point (5, 9). Create the equation for line j.
alisha [4.7K]

Answer:

y = 1/5 x + 8

Step-by-step explanation:

slope of line j: m = -(1/-5) = 1/5

j pass (5,9): (y-9)/(x-5) = 1/5

y-9 = 1/5(x-5) = 1/5 x - 1

y = 1/5 x + 8
