Question

If the line though the point (-4,y) and (1,3) is parallel to the line through the point (0,7) and (-2,5). fine the value of y​

Answer 1

Answer:

$\frac{3 - y}{1 + 4} = \frac{5 - 7}{ - 2 - 0} \\ two \: slopes \: of \: lines \: must \: be \: equal \\ \frac{3 - y}{5} = \frac{ - 2}{ - 2} \\ 3 - y = 5 \\ y = 3 - 5 = - 2$
