Regarding Linear questions

Answer 1

See the attached pictures for the solutions: 

Answer 2

1.
2x + 10 = 30 - x
x = 20/3 = 6.67
y = 70/3 = 23.33333...
Both lines intersect at the 23.33... point

Blue Line: (0,10) , (20/3)(70/3)
Red Line: (0,30) , (12,17)

2.
Slope: (y2 - y1 ÷ x2 - x1)

= (-3 - 5) ÷ 3 - (-1)

= -6 ÷ 4

= -2

Slope = -2

Intercept:

y = mx + b

SLOPE = m

y = (-2x) + b

b = y1 + m

b = 5 + (-2) = 5 - 2 = 3

Intercept  = 3

Hope This HELPS!
