Jemma wants to solve the following system using the elimination method: y = x − 6
y = 6x − 19

What number should the equation y = x − 6 be multiplied by to eliminate x?

a
1

b
2

c
4

d
−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: 1 and 3

step-by-step explanation:
