Linear Function

4. Lines in the same plane that never intersect.They have the same slope but different y-intercepts
6. A function that can be represented by a straight line on a graph.It has the form y=mx+b, ,where m is the slope and b is the y-intercept
8. lines that intersect at a 90-degree angle.their slopes are negative reciprocals of each other
9. Another form of a linear equation,,Ax+by=C,where A,B and C are constants,and A and B are not both zero
10. The point where the graph of a line crosses the x-axis.it’s the value of x when y=0
11. The measure of the steepness of a line. It indicates how much the y-coordinate changes for a given change in the x-coordinate.It’s often denoted by the letter m

1. An alternative form of the equation of a line,y-y1=m(x-x1) where m is the slope and (x1,y1) is a point on the line.
2. by the horizontal change(run) between two points on a line
3. The standard form of a linear equation,y=mx+b,where m is the slope and b is the y-intercept
5. The point where the graph of a line crosses the y-axis.It’s the value of y when x=0, and it's represented as(0,b) on the coordinate plane
7. another way to express slope,it refers to the vertical change (rise)
