Question

Determine the equation of the line with slope 3 that passes through the point M(1, 2).
3x + y = 1
3x - y = -1
3x - y = 1
Ox-3y=-1

Answer 1

Answer:

3x - y = 1

Explanation:

Equation formula:

y - y1 = m(x - x1)

where m is slope, (x1, y1) are coordinates

Find Equation:

⇒ y - 2 = 3(x - 1)

⇒ y = 3x - 3 + 2

⇒ -3x + y = -1

⇒ 3x - y = 1

Answer 2

Equation of line in point slope form

• y-y1=m(x-x1)
• y-2=3(x-1)
• y-2=3x-3
• y=3x-1
• 3x-y=1
