Answer:

AB : \frac{5}{3}

PT : -\frac{1}{5}

Step-by-step explanation:

The line AB passes through A(-2,4) and B(-8,-6) points.

Therefore, the slope of the line AB will be \frac{4-(-6)}{-2-(-8)} =\frac{5}{3} (Answer)

Again line PT passes through P(3,-1) and T(8,-2) points.

Therefore, the slope of the line PT will be \frac{-1-(-2)}{3-8} =-\frac{1}{5}. (Answer)

Here we have applied the formula of slope of a straight line passing through the points (x_{1},y_{1}) and (x_{2},y_{2}  ) as given by \frac{y_{1}-y_{2}  }{x_{1}-x_{2}  }.

Answer:

y = 120

Step-by-step explanation:

If y = 32 when x = 8, then <em>y</em> is 4 times the number of <em>x</em>. If x = 30, then (4)30 = 120.
