One line passes through the points (-7,5)
(−7,5) and (-1,-3) another line passes through points (0,3) and (3,-1)
are the lines perpendicular, parallel or neither ?

Prependicular

Step-by-step explanation:

Since you have 2 points of a line you can find the gradient of each line using (y2-y1)/(x2-x1) or change in y divided by change in x. For line one this is (-3-5)/(-1+7) = -8/6 = -4/3

For line two this is (-1-3)/(3-0) = -4/3

Since they have the same gradients they are in fact parallel

Perpendicular lines will have the negative recpriocal of each other gradient.

step-by-step explanation:

he has 140 chickens because he has 10 times more chickens than ducks and he has 14 ducks so 14*10=140
