Can someone explain to me how to do this?
1 answer:
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:
77.76 times
Step-by-step explanation:
The average distance of Neptune from the sun
= 4.503 × 10 ⁹ k m .
and Mercury = 5.791 × 10 ⁷ k m .
Hence neptune is ( 4.503 × 10 ⁹) ÷ (5.791 × 10 ⁷ ) times farther from the sun than mercury
i.e.( ) × 10⁹⁻⁷ times
= 0.7776 × 10 ² times
= 77.76 times.
