Q:

find the equation for intercept x 4 and y -7​

Accepted Solution

A:
Answer:y = [tex]\frac{-7x}{4} - 14[/tex]Step-by-step explanation:The equation used to find the equation for a line with two intercepts is called point slope form. [tex]y - y_{1} = m(x - x_{1})[/tex] , where [tex]y_{1}[/tex] and [tex]x_{1}[/tex] are the intercept points and m is the slope.However, we need the slope to use this formula. Use [tex]m = \frac{y_{1} - y_{2} }{x_{1} - x_{2}}[/tex]m = \frac{y_{1} - y_{2} }{x_{1} - x_{2}}[tex]m = \frac{((0) - (7))}{((4) - (0))}[/tex][tex]m = \frac{-7}{4}[/tex][tex]y - y_{1} = m(x - x_{1})[/tex]y - ( -7 ) = m ( x - ( 4 ) )y - ( -7 ) = -7/4 ( x - ( 4 ) )y + 7 = -7/4 ( x + 4 )y + 7 = [tex]\frac{-7(x+4)}{4}[/tex]y + 7 = [tex]\frac{-7x-28}{4}[/tex]y + 7 = [tex]\frac{-7x}{4} - 7[/tex]y + 7 = [tex]\frac{-7x}{4} - 7[/tex] - 7y = [tex]\frac{-7x}{4} - 14[/tex]
