Slope intercept form is y = mx + b
The only variables we need to figure out are m and b.
M is the slope, or rise/run. In other words, how much the line rises and then shifts right (runs). Beginning at (-6, -3), the line rises 1 and runs 3 to get to (-3, -2). So m is 1/3 (rise/run). Because the line is moving upwards, the slope is positive.
B is the y-intercept, which is the vertical part of the graph. In this case, b is -1 on the vertical axis.
The answer is y = 1/3x - 1
Answer:
Step-by-step explanation:
Given
Required
The result in standard form
We have:
Remove brackets
Collect like terms
The standard form of a quadratic equation is:
So, we have:
We know that
g=3
r=2
b=5
total marbies=g+r+b------> 3+2+5----> 10
a) <span>probability that the first marble is red
P(red)=r/total marbies------------> 2/10-----> 1/5
b) </span><span>probability that the second marble is blue
in this case total marbles-------> 9
P(blue)=b/total marbles----------> 5/9
c) </span><span>the probability that the first marble is red and the second is blue
(1/5)*(5/9)=1/9
the answer is
1/9</span>
The answers are A & D
good luck
