3. Linear Functions and Slope-Intercept Form
Sign In
What do m and b represent in y=mx+b?
Equation: y=9/2x-5
Slope: 9/2
y' -intercept:' -5
Equations in slope-intercept form follow a specific format, where m represents the slope of the line and b is the y-intercept.
y= mx+ b
LHS+2y=RHS+2y
LHS-10=RHS-10
.LHS /2.=.RHS /2.
Write as a sum of fractions
Calculate quotient
a* b/c=a/c* b
Rearrange equation
a-b = a+(- b)
The given equation is already in this form. Below we have highlighted the slope m and y-intercept b. y= 9/2x+( -5) We can see that the slope is 9/2 and the y-intercept is -5.
