Writing Linear Equations - Kuta Software It's possible to write an equation relating x and y using the slope formula with $$\left (x _\, ,y_ \rht )=\left ( 3,5 \rht )\: and\: \left ( x_,\, y_ \rht )=\left ( x,y \rht )$$ $$m=\frac$$ $=\frac$$\, =\frac$$$\left ( x-3 \rht )=y-5$$Since we used the coordinates of one known point and the slope to write this form of equation it is ed the point-slop form$$y-y_=m\left ( x-x_ \rht )$$Another way of writing linear equations is to use the standard form$$Ax By=C$$Where A, B and C are real numbers and where A and B are not both zero. Period____. Date________________. Writing Linear Equations. Write the slope-intercept form of the equation of each line. 1. −5 −4 −3 −2 −1 0. 1 2 3 4 5. −4.
