How do i solve #13? (linear equations)

#12:

Assuming that I have those points correct: (1, 5) and (-4, -10), the slope of this line is

5-(-10)

m = = 15/5 = 3

1-(-4)

The line passes thru the origin, so the y-intercept is 0.

So the equation of this line is y = 3x.

I see no marks (points) in the illustration for #13.

goog may have it for you

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.
