In the slope intercept form equation of a line (y=ax+b) a represents the slope, and b represents the intercept, which is -5. Thus, we know y=ax-5. The slope can be found by creating a fraction with the change in y value on top, and the change of x value on the bottom. If we have two points (4, 1) and (0, -5) we can put this into a fraction - 
, which simplifies down to -6/-4, or 3/2. Thus the answer is f(x)=

Answer:
0.7% off
Step-by-step explanation:
9.67 × y = 9.6 × 100
9.67y = 960
9.67y ÷ 9.67 = 960 ÷ 9.67
y = 99.2
100% - 99.2% = 0.8%
