15 points only answer if 100% sure when graphed, the x-intercept of a linear function is (-4,0), and the y-intercept is (0,12). which of the following equations represents the function? a. y + 12 = 5(x − 4) b. y − 4 = 4(x + 2) c. y − 6 = 3(x + 2) d. y + 6 = 2(x + 7)

C. y - 6 = 3(x +2)

Step-by-step explanation:

The answer to the question is given in point-slope form:  

Where m = slope and () are a point on the graph.  

The first thing to do would be to find slope.  You can find slope from two points on a graph by using slope formula:

So, the slope=3.  The only equation with a slope of 3 is C. y - 6 = 3(x +2).

You can check your answer by plugging in a given point, for example (0,12) where x = 0 and y = 12:

12 - 6 = 3(0 +2) or 6 = 3(2) or 6 = 6 Since it checks out, we know the equation is the right one.

choice b is correct

step-by-step explanation:

we have been given the following system of inequalities;

we are required to graph the solution to the system of inequalities. using a graphing tool, the graph of the system is as shown in the attachment. the continuous line represents the graph of while the dotted line represents .
