Answer:
The equation is x-2y = -5
Step-by-step explanation:
Using the slope intercept form
We solve this by finding the y-intercept
Point (1,3) , x = 1 and y = 3
- y = mx+b
- y = 1/2x+b
- 3 = 1/2(1) + b
- 3 = 1/2 + b
- 3 - 1/2 = b
- 5/2 = b
Again , substitute the values:
We get the y-intercept form but we will transform it to standard form
Multiply 2 to cancel the denominators
- 2(y = 1/2x + 5/2)
- 2y = 2/2x + 10/2
- 2y = x + 5
- -x + 2y = 5
Multiply -1 to make x positive
- -1(-x + 2y = 5)
- x - 2y = -5
Final answer: x-2y = -5
