For this case we have that by definition, the equation of a line in the slope-intersection form is given by:
Where:
m: It's the slope
b: It is the cutoff point with the y axis
We find the slope with the given points:
Thus, the line is given by:
We substitute a point to find "b":
Finally, the equation is:
Answer:
to find the slope for the first one, use the formula
(It's the slope formula)
so...
then plug in...
this line has a slope of 0
As for the miles problem, to find mph, the miles have to be at 1.
so...
therefore, he drove 60.5 mph
Answer:
60 degrees
Step-by-step explanation:
The angles all have to add up to 180, so you can do
