Step-by-step explanation:
If you are given to different points on a slope you can find the slope by putting in the equation of
(y2-y1)/(x2-x1)
then pick one of the two points and put it in the point-slope formula with the new founded slope
y-y1=m(x-x1)
and then solve for y to get into the form of
y=mx+b m being the slope and b being the y-intercept
-If you are given the slope and just one intercept then just simply put it in the point-slope intercept
Example
Say you're given (-2,-2) and (4,1)
find the slope
x1=-2 y1=-2 and x2=4 y2=1
(1-(-2))/(4-(-2))
=3/6=1/2 this is the m
now put it in the point slope form
y-(-2)=1/2(x-(-2))
y+2=1/2x+1
-2 -2
y=1/2x-1
Answer:
v - r
------ = a
t
Step-by-step explanation:
Starting with v = r + at, subtract r from both sides, so as to isolate the 'at' term:
v - r = r - r + at, or
v - r = at
Next, divide both sides by t, to isolate a:
v - r
------ = a
t
Answer:
The lines would be parallel because their slopes are the same and their y-intercepts are different.
Step-by-step explanation:
First, start with the two equations:
y = 7x + 15
y = 7x + 4
So for lines to be parallel, they must have the same slope. For lines to be perpendicular, one of the lines must be the negative reciprocal of the other. In other words, it should be the opposite sign (+ or -) and the reciprocal (flip the numerator and denominator.
In this case, the lines are in slope-intercept form:
y = mx + b
so the slope is already given.
Slope of line 1 = 7x
Slope of line 2 = 7x
Because these lines have the same slope but different y-intercepts, they would be parallel to each other. You can check this by graphing it.
It says to find the sum of the angle measures in a 16-gon.
We have a formula to find the sum of interior angles of polygon with 'n' sides.
Sum = (n-2)·180°
Here the value of n would be 16 for a 16-gon.
So, sum = (16-2) × 180° = 14 × 180° = 2520°
Hence, the sum of the angle measures in a 16-gon is 2520°
