How do you find the slope of a linear equation with only the numbers they give you?

Hello!

In order to find the slope of a linear equation, you need two ordered pairs from the graph.

Once you have the two ordered pairs, you use the slope formula to find the slope. The formula is: .

With that formula, you assign the ordered pairs to , , , and .

Note that and must be assigned to one of the ordered pairs. and is assigned to the other ordered pair.

Then, you substitute the assigned ordered pairs into the formula and solve for the slope.

x = -4

step-by-step explanation:

- 20 - 4(x + 3) = 4x

=> -20 - 4x - 12 = 4x

=> - 32 -4x = 4x

=> -32 = 4x + 4x

=> - 32 = 8x

=> -32/8 = x

=> -4 = x

solve systems of equations by graphing. a system of linear equations contains two or more equations e.g. y=0.5x+2 and y=x-2. the solution of such a system is the ordered pair that is a solution to both equations. to solve a system of linear equations graphically we graph both equations in the same coordinate system
