Question

A line that includes the point (-8,-3) has a slope of -1/9. What is it’s equation in point-slope form?

Answer 1

1. the formula that represents the equation point- slope is the following y-y1 = m(x-x1) where the point is given (-8,-3) and the slope is -1/9
2. then you mus substitute the values in the equation y-(-3) = -1/9[(x-(-8)] , resolving it y+3= -1/9 ( x+8) , y+3 = -1/9x+9/8, y = -1/9x +9/8-3, y = -1/9x-15/8

of this form the equation that represent the form point-slope is

1. y+3= -1/9 ( x+8)
