# Write an equation of the line through the given points

The students will be able to effectively compute the slope of lines. They will use this knowledge to compare the slopes of parallel and perpendicular lines. The students will be able to write lines in slope intercept form and point slope form. 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.

## Respond to this Question

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.Equation of the Line Calculator Find the equation of the line step-by-step. Example 5: Find the equation of a line passing through the given points.

Use function notation to write the equation. Use function notation to write the equation. Oct 23,  · Write an equation of the line that passes through the given points.. please help? I know how to write an equation of a line, but I need some help with this one.

you have to write one for these two points (2,-1) (3,8) ok so first you have to find the slope and I got 4/0. Status: Resolved. The equation of a line is typically written as y=mx+b where m is the slope and b is the y-intercept. If you know two points that a line passes through, this page will show you how to find the equation of the line.

The student will be able to write the equation of a line given two points. The student will be able to identify slope intercept form and point slope form. The equation is useful when we know: one point on the line ; and the slope of the line, ; and want to find other points on the line.

Let's find how. What does it stand for?

 Report Abuse Find the equation of the line. Write the equation using function notation. Slope and Systems of Equations Math Home Search Dr. Math Finding the Equation of a Line Date: Slope-intercept equation from two points (video) | Khan Academy After this lesson, you will be able to: Given the vertex of parabola, find an equation of a quadratic function Given three points of a quadratic function, find the equation that defines the function Many real world situations that model quadratic functions are data driven. Was this information helpful? Pre- Algebra Given an equation of a line, how do I find equations for lines parallel to it going through specified points Simplifying the equations into slope-intercept form.

(x 1, y 1) is a known point. m is the slope of the line (x, y) is any other point on the line.
