Answer:
The slope is -4
Step-by-step explanation:
slope = (y2-y1)/(x2-x1)
(1-5)/(3-2)
-4/1
-4
The formula for the circumference of a circle is 2πr. r stands for the radius ehich is 1/2 of the diameter (the length from one edge of the circle to another on the inside of the circle). If you are estimating then you will want to change π to three and put that in for pie in the original equation.
Answer: Reflection is the change in direction of a wavefront between two different media so that the wavefront returns into the medium from which it originated.
Step-by-step explanation:
Answer:
first of all the formula
y = mx+c
where m is slope and c is y-intercept.
now substitute the values-
y = 2x - 5
(for the slope here is 2 and the part where the line intercepts y axis is -5
therefore
y = 2x-5
