## Algebra: A Combined Approach (4th Edition)

a. 2 b. 5 c. $x = \frac{20}{3}$
Plug in x= 4: $-\frac{3}{4}$ $\times(4) +5$ = -3+5 = 2 Plug in x= 0: $-\frac{3}{4}$ $\times(0) +5$ = 0+ 5 = 5 Plug in y= 0: 0 = $-\frac{3}{4}$ $\times(x) +5$ $\rightarrow$ -5 = $-\frac{3}{4}$ $\times(x)$ $x = \frac{20}{3}$
