Answer:
B
Step-by-step explanation:
To solve for the slope:
(2-(-3))/(4-2)=5/2
y=5/2x+b
plugin points:
2=5/2(4)+b
2=10+b
b=-8
so equation of the line is y=5/2x-8
and in standrd form its 5x-2y=16
Step-by-step explanation:
Wait, what are you trying to ask?
Answer:
.571
Step-by-step explanation:
We need to find the total number of boys
11+5+4 = 20
And the total number of students
11+7+5+4+4+4 = 35
The Probability that the student is a boy is boy/total
P (boy) = boy/total
= 20/35
=4/7
=.571428571
to 3 decimal places
=.571
