Step 3a) Solve for 'b' Subtract 69 from both sides

-69 =-69 -3b =-21

Step 3b) Divide both sides by -3

-3b =-21 -3 -3 b = 7

Step 2a) Solve using symbolic method

Step 2b)

Linear equations are written in the form y = mx + b, where m is the slope & b is the y-intercept.

 Graph an Equations using Slope & Y-Intercept Video Tutorial http://www.virtualnerd.com/algebra-1/linear-equation-analysis/slope-intercept-form/slope-intercept-form-examples/graph-line-givenslope-intercept

o Graph an Equations using Slope & Y-Intercept Example Graph the equation y = x – 4 Step 1a: Identify the y-intercept (b)

b = -4 so y-intercept is (0, -4)

Step 1b: Plot the y-intercept

Step 2a: Identify the slope of the line (m)

Step 2b: Use the slope to graph at least 2 additional points

m=

so the slope means rise up 2 units and

run right 3 units

o Graph an Equations using a Table Example Graph the equation y = 2x – 2

Step 2a) Create a table to help find ordered pairs. The table will have a column for xcoordinates, a column for plugging our x values into 2x – 2 and a column for our y-coordinates. Since we are not given any x-coordinates, we have to choose some ourselves. It is a good idea to choose one positive number, one negative number and zero as our xcoordinates. Let's choose -1, 0 and 1 for our xcoordinates.

(FYI...You can pick any numbers you like to create coordinates.) Step 2b) Calculate the y-coordinates by substituting each of the x-coordinates into the equation. Use order of operations to find the value of y when x = -1, x = 0 and x = 1

Step 4) Draw a line through your plotted points & add arrows at both ends.
