Step-by-step explanation:
1) 2x + x = 3x
2) 3y - 2y = y
3) 18 + 1 = 19
4) 3x + y = 19
5) y + -1y = 0
6) Divide each side by '3'.
x = 6.333333333 + -0.3333333333y
7) x = 6.333333333 + -0.3333333333y
Answer:
19.5
(x₁, y₁) = (-10, -10) & (x₂, y₂) = (-5, -10)
y-intercept = b = -10
There is no change in y- coordinates. So, the line is parallel to x- axis
Slope = 0
Equation: y = b
y = -10
