Anisia Jackson 9/11/2017 Topic Write-Up Finding the slope using the slope formula with a linear equation Sources: ALKES & YouTube https://www.youtube.com/watchv=5fkh01mClLU Real-life application: When architects create a building, they use the slope-formula to create the roof of the building to a peak. The reason the architects make a peak at the roof so that, rain and snow can fall. They measure the roof to level out the attic of a homes to have rain or snowfall. Architects do this technique to stop roof leaks that can occur. Connection from last topic: When using the slope formula, you have to use a linear equation to have a slope and a y-intercept Examples of linear equations: -2y=5x+6 -2y=x+1 Y=-2 These are examples of linear equations that would be used to find slope intercept. Slope formula y=mx+b m = slope b= y-intercept Find the slope and y-intercept of example 1 in slope from: -2y=5x+6 −2y=5x+6 −2 y 5x 6 −2 =−2 −2 first step you would do, is divide each side by -2. Divide each step by -2 so you can get y by itself. 5x 6 y= + Second step you will divide. −2 −2 y=−5 x−3 2 Finally, you will have your slope form. Now you will need to identify the slope and the y-intercept −5 Slope = x 2 y-intercept = -3
