How to find y intercept of two points

For each set of data, plot the points on graph paper. Make your graph big enough and use a ruler. Then, by eye, draw a line that appears to fit the data. For your line, pick two convenient points and use them to find the slope of the line. Find the y-intercept of the line by extending your line so it crosses the y-axis.

Y = Slope*X + Intercept. In this equation, we have already calculated the slope, but to truly know what would be the Y value for a given X value, you also need to know the intercept. Thankfully, Excel has a formula for that as well, and I will cover how to calculate intercept in all the methods. Method 1: Using the Excel SLOPE FunctionThe Points. We use Cartesian Coordinates to mark a point on a graph by how far along and how far up it is:. Example: The point (12,5) is 12 units along, and 5 units up. Steps. There are 3 steps to find the Equation of the Straight Line:. 1. Find the slope of the line; 2. Put the slope and one point into the "Point-Slope Formula"From there, we can solve for b, and see that b = 0: 2 = 2 + b. 2 - 2 = 2 + b - 2. 0 = b. Since b is 0, our completed equation looks like this: y = 2x + 0. To find the intercepts of this equation, we just substitute a 0 in the right place. To …Writing the Equation of a Line from Two Points. To find the equation of a line when given two points on the line, we first find the slope and then find the y-intercept.

Note that the x-value is always zero. So, plug in zero for x and solve for y:

Why is my freezer not freezing.

The forms y=mx+b and y=mx+a are essentially the same, except for the naming of the constant term. The form y=mx+b means slope m and y-intercept b; similarly, the form y=mx+a means slope m and y-intercept a. The form y=m (x-a) is essentially different from the other two forms, and means slope m and x-intercept (instead of y-intercept) a. The Points. We use Cartesian Coordinates to mark a point on a graph by how far along and how far up it is:. Example: The point (12,5) is 12 units along, and 5 units up. Steps. There are 3 steps to find the Equation of the Straight Line:. 1. Find the slope of the line; 2. Put the slope and one point into the "Point-Slope Formula" These points are called x-intercepts and y-intercepts, respectively. What is the formula for slope and y-intercept? The slope-intercept form of a linear equation is y = mx + b, where m is the slope of the line and b is the y-intercept. To find it, we set the value of ( x ) to zero within the function and solve for ( y ). This approach works because the y-intercept occurs exactly at ( x = 0 ). For a linear equation in the form of ( y = mx + b ), the y-intercept is simply ( b ), since it’s the value of ( y ) when ( x ) is zero. For non-linear equations, the same basic ...You want to get y by itself on one side of the equation, so you need to divide both sides by 2 to get y = 3x - 6; This is slope intercept form, y = 3x - 6.
