Give the linear system 3x + 7y = 20

x - 4y = 9

Identify the values for the elements in the

coefficient matrix.

211 212

A =

What is the size of the augmented matrix for the linear system?

312312

step-by-step explanation:

it has the same slope and a different y-intercept

hope this : )

me! what did you put for this question?

step-by-step explanation:

look at the picture.

y-intercept for the function on a picture is 4 → point (0, 4).

y-intercept for the function

is for x = 0. substitute:

y-intercept is 8 → point (0, 8).
