Question

Write an equation in slope-intercept form of the line with the given slope and point: slope = 3 and (1, -2).

How do I solve this?

Answer 1

y = mx + b
-2 = 3(1) + b solve for b

Once you have b, rewrite the equation y = 3 x + whatever you got

Answer 2

Oh, I see now. Thank you so much!

Answer 3

Alternatively, you could substitute the slope, m, and the point, (1, -2) into the point-slope form of the equation of a straight line, and then solve for y. I tend to favor this approach.

Answer 4

I do, too...it's much easier...fewer steps

Answer 5

y +2 = 3(x-1)
y+2 = 3x+3
y = 3x+1 Is this what you got Maikel?
