Question

Find the equation for the line passing through the points (- 2, 3) and (4, 5). Use the form y = mx + b.


A. y = 3x + 5
B. http://diagnostic.achievementseries.com/cdn//1/_graphics_math_11897t/3244af98-b107-46a2-8fe2-4401005d0f29.gif
C. y = 3x + 9
D. http://diagnostic.achievementseries.com/cdn//1/_graphics_math_11897u/49f54a1b-5759-4d2c-a469-899af5b43db9.gif

Answer 1

Answer 2

\(\sf (x_1, y_1)\)= (- 2, 3)
\(\sf (x_2, y_2)\)= (4, 5)

Slope (m):
\(\sf \Large m =\frac{y_2-y_1}{x_2-x_1}\)

To solve for the y-int or b:

1. Plug the value of m in y=mx+b
2. Plug any of the given point in the equation.
3. Solve for b.
4. Plug b into y=mx+b

Answer 3

o ok thanx

Answer 4

so what did you get for m?
I'll still guide you until you get it, just to make sure you really understand ;)
