Question

Given the point (3,-4) & slope = 2, what is the equation of the line?

Answer 1

Explanation:

So use the point slope formula: y-y1=m(x-x1)

substitute y1 and x1 with the points and m with the slope: y-(-4)=2(x-3)

y+4=2(x+3).

This is Point-slope form.

you can go on if you want: y+4=2x+6(I multiplied 2 by x and 3)

subtract 4 from both sides: y=2x+2

This is slope-intercept form.
