$\Huge{\bf{Distance\ Between\ Two\ Points:}}$ Let (x1,y1) and (x2,y2) be any two points.Then the distance between the two points is given by: $D=\sqrt{(x _{2}-x _{1)^2+(y _{2}-y _{1})^2}}$ **************************Lets take an example***************************************** Example 1) Find the distance between the points (4,5) and (2,1) Solution : (x1,y1)=(4,5) and (x2,y2)=(2,1) Lets Use the formula, $D=\sqrt{(x _{2}-x _{1)^2+(y _{2}-y _{1})^2}}$ $D=\sqrt{(2-4)^2+(1-5)^2}$ $D=\sqrt{(-2)^2+(-4)^2}$ $D=\sqrt{4+16}$ $D=\sqrt{20}$

$\Huge{\bf{LINEAR\ FUNCTION:}}$ A function described by the equation $y=mx+c$ or $f(x)=mx+c$ is called a linear function. Where, m=slope c=y-intercept Note:The y-intercept is the value of y when x=0.

$\Huge{\bf{SLOPE :}}$Let (x1,y1) and (x2,y2) be the two distinct points on a straight line such that x1is not equal to x2,then $m=y_2-y_1/x_2-x_1$
