Question

Anyone any good at math?

Is the relationship shown by the data linear? If so, model the data with an equation

Answer 1

yes the x increases by 6 and the y decreases by 3.

y = -1/2x - 7/2

Explanation:

find the slope :

(1,-4), (7, -7)

y2- y1 / x2 - x1

substitute those numbers and you get -1/2.

point slope form :

y - y1 = m(x- x1)

y - (-4) = -1/2 ( x - (1))

y+4 = -1/2(x-1)

slope intercept form :

y = -1/2x - 7/2

does this help ?
