the points (7,2)and (-1,0) lie on a line ? |
| Answer» The given points are (7, 2) and (-1, 0)The slope of the line is given by{tex}m=\\frac{y_2-y_1}{x_2-x-1}{/tex}Substituting the values{tex}m=\\frac{0-2}{-1-7}\\\\\\\\m=\\frac{-2}{-8}\\\\\\\\m=\\frac{1}{4}{/tex}Point slope form of a line is given by{tex}y-y_1=m(x-x_1)\\\\\\\\y-2=\\frac{1}{4}(x-7)\\\\\\\\4y-8=x-7\\\\\\\\4y=x+1{/tex}\xa0 | |
