Answer:
y = -3
Step-by-step explanation:
{y = x/2 - 4
y = 1 - 2 x
Substitute y = x/2 - 4 into the second equation:
{y = x/2 - 4
x/2 - 4 = 1 - 2 x
In the second equation, look to solve for x:
{y = x/2 - 4
x/2 - 4 = 1 - 2 x
Add 2 x + 4 to both sides:
{y = x/2 - 4
(5 x)/2 = 5
Multiply both sides by 2/5:
{y = x/2 - 4
x = 2
Substitute x = 2 into the first equation:
{y = -3
x = 2

y = -3
No. 2.5:3.5 would be either proportional to 12:16.8 or 3.571428( which is 25/7);5
Answer:
y = 4x - 1
Step-by-step explanation:
y = mx + b
Here m is slope and b is y-intercept
m = 4; b = -1
y = 4x - 1
