Question

Write an equation in a point-slope form that passes through the given point with the given slope (3, 5), m = -4 and-1, 8), m = ½

Answer 1

`\large\boxed{y-5=-4(x-3)}\\\boxed{y-8=(1)/(2)(x+1)}`

Explanation:

The point-slope form of an equation of a line:

`y-y_1=m(x-x_1)`

m - slope

`m=-4,\ (3,\ 5)\\\\y-5=-4(x-3)`

`m=(1)/(2),\ (-1,\ 8)\\\\y-8=(1)/(2)(x-(-1))\\\\y-8=(1)/(2)(x+1)`
