Using the formula for lines y=mx+b
To find out the gradient of the line, we do (y2-y1)/(x2-x1).
(3-6)/(-1-2)= -3/-3= 1 is the slope of the line
So far, y=(1)x+b
Now substitute one of your given coordinates into this equation:
6=2+b
b=4
Therefore, the equation of the line is y=x+4
150*1=150
150/7200=.02 km per second
7/2 is the reciprocal of 2/7
Answer:
x = 8/3 or 2 2/3
Step-by-step explanation:
if angles A and B are complementary then their sum is 90 degrees
we can write the following equation to find 'x':
3x + 4 = 6x - 4
subtract '3x' from each side:
4 = 3x - 4
add 4 to each side:
8 = 3x
divide each side by 3:
8/3 = x
or x = 2 2/3
