1 answer:

5 0

(13.4 + 2.3y + 5.2) - (29.8 - 3.5y + 7.1)
(18.6 + 2.3y) - ( -29.8 - 3.5y)
18.6 + 2.3y + 29.8 + 3.5y
18.6 + 29.8 + 2.3y + 3.5y

2x - 4y = 8 → -4y = -2x + 8 → y = $\frac{1}{2} x$ - 2

We know the slope (m) = 4, need to find y-intercept (b)

y = 4x + b

$\frac{1}{2} x$ - 2 = 4x + b

$\frac{1}{2} (6)$ - 2 = 4(6) + b

3 - 2 = 24 + b

1 = 24 + b

-23 = b

Equation: y = 4x - 23
