answer:
y = 2x - 5
work:
to write equations, we use the format y = mx + b.
m stands for the slope, and b stands for the y intercept.
this means that you should be able to enter the values for y and x and get a valid equation as a result.
in this equation, we are not given a y intercept value, but we do have a slope and x and y values, so we have to solve by substituting.
so, let's substitute in the values of y and x and the slope,
and solve for b, the y intercept.
1 = 2(3) + b (multiply 2 x 3)
1 = 6 + b (subtract 6 from both sides)
- 5 = b
b has a value of -5. let's place this into the equation.
y = 2x - 5.
the slope is 2, and the y intercept is -5, let's plug in our y and x values to verify that this is true.
1 = 2(3) - 5
1 = 6 - 5
1 = 1
so, this equation is correct. hope this helps and have a great day!
Not if it ends at 9, like you typed it.
Answer: A
Step-by-step explanation: This is because the first line goes forward 4.5 and the second line moves it back 2.5 and 4.5-2.5 is 2 which is the endpoint of answer a
Answer:
1/6
Step-by-step explanation:
number cube 6 faces less than 2, only 2 possibilities, leaving us with a fraction of 2/6=1/3
tails is a 50 percent chance or 1/2
3/6 time 2/6
equals:
1/6
the probability of rolling a number less than 2 and flipping tails on a coin is 1/6
find probability of event a: number cube and multiply it by probability of event b: coin
The answer is A. y < -2x + 4 and y > 3x - 4.
