Answer:

y = 4x/3 + 16

Explanation:

Since the point new line is parallel to the line 4x - 3y = 5, so it must have the same slope. We now write this equation in slope-intercept form

4x - 3y = 5

-3y = -4x + 5

y = 4x/3 - 5/3

Its slope is the coefficient of x. So, its slope is 4/3 which will be the slope of the new parallel line which passes through the point (-6, 8).

To find the equation of this line, we use

(y - y₀)/(x - x₀) = m where x₀, y₀ are the points which the line passes through and m = slope of line. Given that ( x₀, y₀) = (-6, 8) and m = 4/3, we substitute these values into the equation. We have

(y - y₀)/(x - x₀) = m

(y - 8)/(x - (-6)) = 4/3

(y - 8)/(x + 6) = 4/3

cross-multiplying, we have

3(y - 8) = 4(x + 6)

Expanding the brackets, we have

3y - 24 = 4x + 24

collecting like terms, we have

3y = 4x + 24 + 24

3y = 4x + 48

In slope-intercept form, it is

y = 4x/3 + 48/3

y = 4x/3 + 16
