Slope Intercept Equations :
Slope Intercept Equations Y=mx+b is the slope intercept form of a linear equation.
X and Y are variables
M is the slope of the graphed equation
B is the value of y where the graph crosses the y-axis
Finding slope from equations :
Finding slope from equations Coefficient – the number by which a variable is multiplied (ex. 3 is the coefficient of 3X)
Slope is the coefficient of X when the equation is in slope intercept form.
Finding slope in equations :
Finding slope in equations If your equation is y=3x-7 your slope is 3
If there is a sign or an operation symbol in front of the coefficient you must include it.
If your equation is y=-5x+2 the slope is -3
If your equation is y=10-8x the slope is -8
Finding slope in equations :
Finding slope in equations If the y variable is not isolated, you cannot find slope until it is isolated.
Y+3x=2 – you must isolate y on a side by itself
y+3x=2
-3x -3x
y=2-3x
The slope in this equation is -3
Finding slope in equations :
Finding slope in equations Sometimes you will have more than one step
16x-4y=24
Move the x -16x -16x
Work vertically -4y=24-16x
Divide all by -4 ÷-4 ÷-4
y=6+4x (-16 ÷-4=4)
The slope is 4
