3. Linear Functions and Slope-Intercept Form
Sign In
What do m and b represent in y=mx+b?
Equation: y=-1/2x-3/4
Slope: -1/2
y' -intercept:' -3/4
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+y=RHS+y
LHS-3/4=RHS-3/4
Rearrange equation
a-b = a+(- b)
Below we have highlighted the slope m and y-intercept b. y= -1/2x+( -3/4) We can see that the slope is - 12 and the y-intercept is - 34.
