Answer:
You can put this equation into point slope formula which is…
y-y1= m(x-x1)
Whilst m is slope
x1 and y1 (x1, y,1)
So in this case lets find the slope first.
Slope is calculated by y2-y1/ x2-x1
Can be any point.
7-(-1) / 1-(-3)
Which is
2
Slope is 2
So plug it in.
y-(-1)= 2(x-(-3)
Solve
y+1= 2x+6
isolate y
Y=2x+5
Your equation is y=2x+5
Answer:
The theoretical probability is smaller than the relative frequency
Step-by-step explanation:
6-sided cube rolled 200 times
Probability of an even number is 1/2= 0.5
200*1/2= 100- theoretical probability
Experimental frequency= 115
Relative frequency= 115/200= 0.575
0.575 > 0.5
The theoretical probability is smaller than the relative frequency
Apply the Pyth Thm twice:
diagonal of base is sqrt(4^2+6^2).
Then the length of diagonal AB is L = [sqrt(4^2+6^2)]^2 + [sqrt(1)]^2
