Converting Linear Equations in Standard form to Slope-Intercept Form (and vice versa)
Error: No decimals allowed ( 0.75 )
In order to graph we only need to plug in two points to draw the line.
so,

DESCRIBE a linear EQUATION: slope, intercepts, etc
Equation
describes a sloping line. For any
equation ax+by+c = 0, slope is
.
X intercept is found by setting y to 0: ax+by=c becomes ax=c. that means that x = c/a. -2/0.75 = -2.66666666666667.
Y intercept is found by setting x to 0: the equation becomes by=c, and therefore y = c/b. Y intercept is -2/-1 = 2.
Slope is -0.75/-1 = 0.75.
Equation in slope-intercept form: y=0.75*x+2.
