Write an equation in Slope Intercept Form for the following line.
2 answers:
Answer:
The equation in slope intercept form (y = mx + b) is y = 2x - 4
m = the slope
b = the y intercept
The line cross the y-axis at -4 so the y-intercept (b) is -4.
You can use the slope formula since you have plotted points (0, -4) and (2, 0) on the graph that you can plug in.
=
= 2
So the slope (m) is 2. Now you can make the slope-intercept form using these values. So, the equation for the line is y = 2x - 4

Answer:
2.48×10^13 miles
Step-by-step explanation:
There are about (365.25 days)(86400 seconds/day) = 31,557,600 seconds in one year. There are 1609.344 meters in one mile. So, the conversion can be written as ...
(4.22 ly) (3×10^8 m/s) (3.15576×10^7 s/yr) / (1.609344×10^3 m/mi)
= 4.22×3×3.15576/1.609344×10^(8+7-3) mi
≈ 24.8×10^12 mi
4.22 light years is about 2.48×10^13 miles
