Summary Students learn about four forms of equations: They graph and complete problem sets for each, converting from one form of equation to another, and learning the benefits and uses of each. Engineering Connection The idea of slope as the rate of change is essential to understanding how lines are graphed.

Let's quickly review the steps for writing an equation given two points: Find the slope using the slope formula. Write the equation using the slope and y-intercept. Ok, now let's apply this skill to solve real world problems. Now you will have to read through the problem and determine which information gives you two points.

Remember a point is two numbers that are related in some way. Also remember, that when identifying a point from a word problem, "time" is always the x-coordinate. In the first year, there were 35 participants. In the third year there were 57 participants.

Write an equation that can be used to predict the amount of participants, y, for any given year, x. Based on your equation, how many participants are predicted for the fifth year?

Identify your two points. This can be written as 1,35 In the third year, there were 57 participants.

This can be written as 3, Therefore, our two points are 1,35 and 3,57 Let's enter this information into our chart. Now that we have an equation, we can use this equation to determine how many participants are predicted for the 5th year. All we need to do is substitute! We will substitute 5 for x x is the year and solve for y.Slope-Intercept Form Answer Key.

Instructions: Write the equation of the line in slope-intercept form. Algebra I Point-Slope Form Worksheet Give an equation in point-slope form that satisfies the given information.

1. Passes through (2, 3) and has slope of –½.

2. Passes through (-1, 4) and m = 4. 3. Passes through (0, 2) and has slope of –5/3. 4. Passes through (4, -2) and m = 0. 5. Notes — Writing Linear Equations in Slope-Intercept Form [j Identify the initial value (y-intercept) from a table, graph, equation, or verbal description.

Use the slope and y-intercepts to write a linear function in the form y = mx+ b from any. Algebra I Name: _____ Slope Intercept Form Worksheet 1 What is slope intercept form?

_____ What does the represent: _____. Worksheet by Kuta Software LLC ©G S2F0T1n5e `KmuqtMac qS^ovfBtHwja]rNea mLbLjCr.h m GA[lvlu IrIi_gNhPtvsb mrWevsieHrzvXevdEPart I: Write the slope-intercept form of the equation of each line given the slope and y-intercept.

1) Slope = -4, y-intercept = 42) Writing Linear Equations Review. This is the equation of x a vertical line whose slope is undefined. 11) Find the equation of a line that passes through the points (5, 3) and (2).

Answer: y 3.
