anonymous one year ago HELP! Write an equation in standard form that passes through points (-4,10) and (0,-5).

A. 15x-4y=20 B. 4x-15y=20 C. 15x+4y= -20 D. 4x+15y= -20

can you find the slope of the line?

3. anonymous

once you have the slope, equation of line is: $y - y_1 = m(x - x_1)$ $(x_1 , y_1) = (0,-5)$

4. anonymous

I'm confused.

How do I find the slope?

Hello @cheymariee , do you still need some help?

7. anonymous

Yes I do.

you will find the slope using $m=\frac{ y _{2}-y _{1} }{ x _{2}-x _{1} }$ just substitute you points.. so lets say that your first x coordinate is 0, and your first y coordinate is -5. the points (-4,-10) will be your second x and y coordinate...

$slope = m = \frac{y_2 - y_1}{x_2 - x_1}$ rise over run
