Pls help ty What is the equation of the line that is horizontal and passes through point (−7.8, 2.9)?

y = 2.9

Step-by-step explanation:

Horizontal lines have the same y-values for any x-value, so if the line passes through the point (-7.8, 2.9) it must have the same y-value of 2.9 for every other x-value, hence y = 2.9

the required function is .

step-by-step explanation:

from the given table it is noticed that the graph passing through (-3,7), (0,4), (3,1) and (8,-4).

it is a linear function because the value of y is decrease by one as the value of x increase by 1.

the slope of the function is

the slope of the function is -1 and the y-intercept is 4.

the slope intercept form is

where, m is slope and b is y-intercept.

therefore the required function is . the graph of this function is shown below.
