Step-by-step explanation:
slope intercept form: y = mx + b ............where m is slope and b is y-intercept
<u>1st question:</u>
4x + y = 1
y = 1 - 4x
y = -4x + 1
<u>2nd question:</u>
x + 2y = 9
2y = 9 -x
y = (-x + 9)/2
y = 
Answer:
Step-by-step explanation:
The equation is 3x - 5y =20.
Suppose we start with (5, y). What value of y is a solution of this equation?
Substitute 5 for x in 3x - 5y =20, obtaining: 3(5) - 5y = 20.
Then -5y = 5, and y = -1. Thus, (5, -1) is a solution of 3x - 5y =20.
Next:
We have (x, 2). Find the value of x that makes (x, 2) a solution of 3x - 5y =20.
Replace y with 2: 3x - 5(2) =20
Then 3x = 30, and x = 10. So (10, 2) is a solution of 3x - 5y =20.
