1. The coordinates of the equation is given (2,4) , (4,10)
The equation formed from the coordinates is
[tex]y-4=\frac{10-4}{4-2}(x-2)[/tex][tex]y-4=\frac{6}{2}(x-2)[/tex][tex]y-4=3x-6[/tex][tex]y=3x-2[/tex]
The equation formed is y=3x-2.
2. The equation for the given coordinates f(-4)=18, and f(4)=2 is
[tex]y-18=\frac{2-18}{4+4}(x+4)[/tex][tex]y-18=-2(x+4)[/tex][tex]y=-2x-8+18[/tex][tex]y=-2x-10[/tex]
The equation formed is y=-2x-10.
3. The equation formed from x intercept at (-5,0) and y intercept at 0,4)
[tex]y-0=\frac{4-0}{0+5}x+5[/tex][tex]y=\frac{4}{5}x+5[/tex]
The equation formed is
[tex]y=\frac{4}{5}x+5[/tex]
