Step-by-step explanation:
<u>The Slope of a Line
</u>
Suppose we know a line passes through points A(x1,y1) and B(x2,y2). The slope can be calculated with the formula:
It's given the points (1,3) and (-2,2). Let's calculate the slope:
Calculating:
The slope of the line is
Answer:
y = 7/5x + 4
Step-by-step explanation:
use the slope from the equation -5/7 and take the negative reciprocal to get the perpendicular slope = 7/5. Then use the equation y=mx+b. Plug in x and y from the point given and the new slope and solve for b.
(-3) = (7/5)(-5) + b, (-3) = -7 + b, add 7 to both sides. b = 4. Rewrite the equation now to be y = 7/5x + 4
Square root 62.8. Which will give you 7.9.
7.9 divided by pi times 5.
7.9 divided by 15.7.
The radius would be 1.9 if left as a decimal, but rounded to the whole number would be 2.
Hope this helps and answers your problem!!!
