What is the equation of line with a slope of 3 that goes through the point (1, -3)

y=mx+b      (plug the points into the equation)

-3=3(1)+b

-3=3+b

b= -3-3

b= -6

the equation is y=3x-6

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.

answer: .75 km
