The ordered pairs (-4,7) and (8,-20) are points on a linear function. which equation best describes this function? f(x) = 13/4x - 46 f(x) = -9/4x - 2 f(x) = - 27/4x + 34 f(x) = 9/4x - 38

First using the given points we need to find the slope of the line.



So, the slope of the line is -9/4

Using the slope and a point we can write the equation of line in slope-intercept form as:



So the correct answer to this question is option B

Period is the time it takes for one “cycle” to complete. in the parent sine function, period is 2*pi since sin(0) = 0, sin(pi/2) = 1, sin(pi) = 0, sin(3pi/2) = -1, and sin(2pi) = 0. at that point, the sequence repeats itself. i’m not sure if your graph is similar to the sine function since you didn’t provide a picture, but you can find the period by looking at a graph.
