Which is the equation of the line passing through the points A(3, -3) and B(-4, 11)?

y = -6x + 3

y = -2x + 3

y = 9x − 3

y = 4x − 9

use the formula$$y=mx+c$$where$$y=vertical~axis$$$$x=horizontal~axis$$$$m=slope$$$$c=y-intercept$$

Find the slope of that line.  There's a standard formula for finding slope when you're given two points.  What is that formula?  

Once you have the slope, write out the "point-slope" formula for a straight line, substituting the coordinates of one of the points (doesn't matter which one).

MARC and I have chosen to recommend different forms of the equation for a straight line, but that's perfectly OK.  Both forms will work.

First find the formula for slope using the given points
formula for slope is$$m=\frac{ y_2-y_1 }{ x_2-x_1 }$$

anonymous · Answer

$$Let~say~A(3,-3)=(x_1,y_1)$$$$Let~say~B(-4,11)=(x_2,y_2)$$substitute the value into the slope formula
