Step-by-step:
Use slope formula to find the slope. (y - y)/(x - x)
Make sure the x and y in front of the minus is a pair that goes together, as well as the x and y behind the minus sign. So
8 - -4 goes on top, that's 12
0 - -1 goes under, thats 1
12/1 is the slope which is just 12. Use either point to fill in the second x and the second y in the point-slope equation. m is the slope.
y - y = m(x - x)
y - 8 = 12(x - 0)
y - 8 = 12x
That is a 180 degree angle (the straight line) and one angle is 78, so you subtract 78 from 180
So the angle would be 102 degrees
It’s “725”, just subtract it by 65..
Answer:
If you need the y-intercept of that equation it is 5
Step-by-step explanation:
subtract the 5x to the other side to get y=-5x+5
Answer: The system of equations has no solutions.
Step-by-step explanation:
Identify the equation as:
[Equation 1]
[Equation 2]
[Equation 3]
Multiply [Equation 1] by -2 and add this to [Equation 2] :
Find another equation of two variables: Multiply [Equation 3] by -2 and add this to [Equation 2]:
Then you get this new system of equations. When you add them, you get:
Since the obtained is not possible, the system of equations has no solutions.
