Find the slope of a line that passes through the points (2, –3) and (–1, 4).

nincompoop · Answer

first solve for the slope then use the y-intercept form to get the equation

nincompoop · Answer

do you know how to solve for the slope @SleepEatRugby

the_fizicx99 · Answer

M = y2 - y1/X2 - x1

sweetburger · Answer

use point slope

nincompoop · Answer

@sweetburger @tHe_FiZiCx99  I got this... you two can calm down

sweetburger · Answer

point slope form i tell you

@nincompoop oki :(

nincompoop · Answer

@SleepEatRugby you need to respond

anonymous · Answer

I keep getting a negative number as the denominator for the slope would this be wrong?

nincompoop · Answer

show me how you are solving for the slope

anonymous · Answer

(4 - -3)/2 + (-1 - 2)/2

nincompoop · Answer

$$slope=m=\frac{ rise }{ run }=\frac{ \Delta y }{ \Delta x }=\frac{ y_2-y_1 }{ x_2-x_1 }=\frac{ 4-(-3) }{ -1-2 }$$

nincompoop · Answer

where are you getting the denominator 2? I think your mixing up mid-point and slope formulas

nincompoop · Answer

then whatever your m (slope) is plug it into the point-slope form 
$$y-y_1=m(x-x_1)$$
use either (2, -3) or (-1, -4) as your x1 and y1
