Find an equation of the line having the given slope and containing the given point. Solve for y.

m = five sixths​, ​(9​, -2​)

1 answer

To find an equation of the line, we can use the point-slope form, which is given by:

y - y₁ = m(x - x₁)

where m is the slope and (x₁, y₁) is the given point.

In this case, the slope is five sixths (5/6), and the given point is (9, -2).

Substituting these values into the point-slope form:

y - (-2) = (5/6)(x - 9)

Simplifying:

y + 2 = (5/6)(x - 9)

To solve for y, we need to isolate it on one side of the equation. We can start by distributing the (5/6) to the terms inside the parentheses:

y + 2 = (5/6)x - (5/6)(9)

Simplifying:

y + 2 = (5/6)x - 15/2

Next, we can move the constant term (2) to the other side of the equation by subtracting it from both sides:

y = (5/6)x - 15/2 - 2

Simplifying:

y = (5/6)x - 15/2 - 4/2

Combining like terms:

y = (5/6)x - 19/2

Therefore, the equation of the line with a slope of five sixths and containing the point (9, -2) is y = (5/6)x - 19/2.
