Question

What is the equation of a line when slope is -6 and is passes through point (1,-2)?

Question 9 options:

y = -6x - 2


y = -6x + 2


y = -6x + 4


y = -3x + 4

Answer 1

• C) y = - 6x + 4

--------------------------

We are given the slope and a point on the line.

Use the point-slope equation to find the equation of the line:

• y - y₁ = m(x - x₁)

Substitute -6 for m and 1 for x₁ and -2 for y₁:

• y - (-2) = -6(x - 1)
• y + 2 = - 6x + 6
• y = - 6x + 4

The matching choice is C.
