Book.
AI 7.0 I will be able to verify that a point lies on a line, given an equation of the line and be able to derive linear equations by
using the point-slope formula.
Linear Equation~ is an algebraic equation in which each term is either a constant or the product of a constant and a single variableY- Intercept-A point where the graph of a function or relation intersects with the y-axis of the coordinate system.X- Intercept~ When a point crosses the X axis on a coordinate gridPoint Slope Formula: y-y1=m (x-x1)

How do you find the linear equation when given two points?
What is point slope form?
Notes Cont.1
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, you can find the linear equation. Y-y1=m(x-x1)It refers to the method for graphing a linear equation on an x,y axis.Example: Point-(4,3) and slope is 2Step 1: Plug in the given values into your point slope formula above. Your point (4,3) is in the form of x1,y1.
Step 2: Your slope was given to you, so where you see M, use 2
Final result should be: y-3=2(x-4) y-3=2x-8 +3 +3 y = 2x-5
Is an algebraic equation in which each term is either a constant or the product of a constant and a single variable
There are two different variations to find the answer, but one way is by plugging in the points. The other is by graphing the formula and seeing if it works for the equation.
Example 1: Can you plug (4,10)into the equation Y=2x+2 and successfully get an equal answer?
