Answer 2

M=y2-y1/x2-x1
= 9-2/3-(4)
=7/7 or 1

Answer 3

Agreed.

Answer 4

The slope of a straight line passes through two points is calculated from the relation:
\[m=\frac{ y_2-y_2 }{ x_2-x_1 }=\frac{ 9-2 }{ 3-(-4) }=\frac{ 7 }{ 7 }=1\]
This is obvious that the line has an angle of 45 with x-axis.

Sp we can choose the first choice (A)
