<h2>
x = 2 and y = - 3</h2>
Step-by-step explanation:
The given system of linear equations:
x - 2y = 8 ........ (1)
and 4x + y = 5 ........ (2)
To find, the values of x and y = ?
Multiplying equation (2) by 2, we get
2(4x + y) = 5 × 2
⇒ 8x + 2y = 10 ........ (3)
Adding equations (1) and (3), we get
x - 2y + (8x + 2y) = 8 + 10
⇒ x - 2y + 8x + 2y = 8 + 10
⇒ 9x = 18
⇒ x = 2
Put x = 2 in (1), we get
2 - 2y = 8
⇒ 2y =2 - 8
⇒ 2y = - 6
⇒ y = - 3
∴ x = 2 and y = - 3
I think it is B
Hope my answer help you?
Answer:
Slope: -2
Y-Intercept: (0,1)
Step-by-step explanation:
The slope would be m. In this case our m is -2, so our slope is -2.
For the y-intercept, you just look at the constant. So our constant is 1, so the y-intercept is (0,1)
