+769 The equation of the line below can be expressed in the form
\frac{x}{a} + \frac{y}{b} = 1.
Find a.
The lines passes through (5,8) and (-4,17).
+37147 Find slope m = (8-17) / (5- -4) = -9/9 = -1
y = mx + b then becomes
y = -x + b sub ineither of the points to solve for b = 13
y = -x + 13
x+y = 13
1/13 x + 1/13 y = 1 a = 1/13
