A) is the correct answer.

The first equation becomes 3x-y=-2.
The second becomes 5x+y=6.

Using the coefficients of x and y, and separating the constants results in the first augmented matrix.

7. What are the slope and y-intercept of y=3x-5?

skelet666 [1.2K]

Answer:

slope = 3

y-intercept = -5

Step-by-step explanation:

y = mx + b

m = slope; b = y-intercept

y = 3x - 5

y = 3x + (-5)

m = 3 = slope

b = -5 = y-intercept
