What information can you learn from the slope-intercept form of an equation?
Equations written in slope-intercept form follow a specific format.
y= mx+ b
In this form, m represents the slope of the line and b represents the y-intercept.
Since the given equation is not in slope-intercept form, let's rewrite it so that it will be easier to identify the slope and y-intercept.
LHS+1/2x=RHS+1/2x
Add terms
1/b* a = a/b
LHS * 8=RHS* 8
a/8* 8 = a
Distribute 8
Multiply
Calculate quotient
Commutative Property of Addition
Below we have highlighted the slope m and y-intercept b. y= 4x+ 6 The slope is 4. The y-intercept is 6, so the graph crosses the y-axis at the point (0, 6).
A slope of 4 means that for every 1 unit we move in the positive horizontal direction, we move 4 units in the positive vertical direction. m= 4/1 ⇔ rise/run=4/1 To graph the equation, plot the y-intercept and then use the slope to find another point on the line.
