find the slope of all the equations
equation 1: 2x-4y=16
equation 2: y=-3/4x-3
equation 3: y-5=-2(x+1)
To find the slope of an equation in the form y=mx+b, where m is the slope, you can directly read the value of m.
Using this formula, let's find the slopes of the given equations:
Equation 1: 2x-4y=16
Rearranging the equation in the form y=mx+b, we get:
-4y = -2x + 16
Divide both sides by -4:
y = 1/2x - 4
The slope of Equation 1 is 1/2.
Equation 2: y=-3/4x-3
The slope of Equation 2 is -3/4.
Equation 3: y-5=-2(x+1)
Expanding the brackets:
y - 5 = -2x - 2
Rearranging the equation in the form y=mx+b:
y = -2x + 3
The slope of Equation 3 is -2.
