Question

What is the point slope form of the line with slope 2/5 that passes through the point (−4, −7) ?

Answer 1

y + 7 = $\frac{2}{5}$ (x + 4)

the equation of a line in ' point- slope form ' is

y - b = m(x - a)

where m is the slope and (a, b ) a point on the line

here m = $\frac{2}{5}$ and (a , b ) =( - 4, - 7)

y + 7 = $\frac{2}{5}$ (x + 4) → equation in point- slope form
