What is the equation of the line that passes through the point<br> (5,-2) and has a slope of 6/5
LenKa [72]

Answer:

y = \frac{6x}{5} - 8

Step-by-step explanation:

given slope m = \frac{6}{5}

point (5, -2) for (x1, y1)

equation for point slope form

y - y1 = m(x- x1)

y - (-2) = \frac{6}{5} (x -5)

y + 2 = \frac{6}{5}x - 6, simplify

y = \frac{6x}{5} - 8,

further you can multiply by 5 to get rid of fraction

5y = 6x - 40
