What are the values of x and y in the matrix equation below?

x = - 3, y = ± 4

Step-by-step explanation:

Add corresponding elements and equate to corresponding element on right side, that is

x + 4 - 9x = 28

- 8x + 4 = 28 ( subtract 4 from both sides )

- 8x = 24 ( divide both sides by - 8 )

x = - 3

----------------------------------------------------

y² + 1 - 17 = 0

y² - 16 = 0 ( add 16 to both sides )

y² = 16 ( take the square root of both sides )

y = ± = ± 4

the slope of the line is 60

one point on the line is (40,10)

step-by-step explanation:

in the equation outside the parenthesis the equation always tells you the slope. in this case it is 60.

in the parenthesis is also says 40 which is x because it is near the x and 10 is y because it is near y.

hi there!
