(a) This line passes through \( (-1.25) \). Find the value of \( a \). (b) On a piese of graph paper, draw the grapth \( a x+2 y=3 \) for \( -3 \leq x \leq 3 \). (c) Find the value of \( y \) when \( x=2.5 \) (d) On the same graph, draw the line \( y=28 \) (e) Find the coordinates of the point where both lines intersect.

Quick Answer
(a) Cannot determine \( a \) without additional information.
(b) Graph the line \( ax + 2y = 3 \) using points \( (0, \frac{3}{2}) \) and \( (3, \frac{3 - 3a}{2}) \).
(c) \( y = \frac{3 - 2.5a}{2} \) when \( x = 2.5 \).
(d) Draw a horizontal line at \( y = 28 \).
(e) Intersection point: \( \left(\frac{-53}{a}, 28\right) \).
