Consider two points in a two dimensional coordinate plane
As you know mid point of a line joining two points is the coordinate of the middle point of only that portion of line joining between two points.
[tex]\text { Mid point of } (x_{1},y_{1})\text { and } (x_{2},y_{2}) =(\frac{x_{1}+x_{2}}{2} ,\frac{y_{1}+y_{2}}{2})[/tex]
As we know distance formula gives the Distance between line joining two points in two dimensional coordinate system.It is always positive.
[tex]\text { Distance formula between two points } (x_{1},y_{1})\text { and } (x_{2},y_{2}) =\sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1})^2}[/tex]
Distance formula gives the distance between two points, whereas Mid point formula gives coordinate of the middle point.
To find the slope, you can use the formula: . Start at where the graph intersects at the y-axis, which is -4. So, it rises up 2 units and goes left 3 units, which makes the slope
.
To find the y-intercept, you would start at where the graph intersects at the y-axis, which is -4 and this would be the y-intercept.
To find the equation, you can use the formula: y = mx + b. m is slope and b is the y-intercept. Plug the slope and y-intercept you found earlier. Thus, your final answer should be:
