Step-by-step explanation:
first you need m and m is -15/5 that means -3
your function is mx =y so your function is -3x= y
Answer:
a=50 degrees
Step-by-step explanation:
Look at the triangle in the middle. You can find two missing angles to calculate the third one.
50 and 130 are supplementary, so 50 must be the upper right angle. The angle opposite to 80 has to be equal to it, of the upper left angle is 80.
A triangle is 180 degrees total, and 180-(50+80)= 50.
The missing angle for the triangle is 50, and since "a" is opposite to it, the values are equal.
a=50 degrees
Hello!
To the value of b, or the y-intercept, we need to substitute an ordered pair/point into the given equation.
Since we are given two points, we can use those two points to find two different equations.
Remember that ordered pairs are written as (x, y).
A(-2, 4)
y = -3x + b
4 = -3(-2) + b
4 = 6 + b (subtract 6 from both sides)
-2 = b
A) Therefore, the equation of the first ordered pair is y = -3x - 2.
B(5, 2)
2 = -3(5) + b
2 = -15 + b (add 15 to both sides)
17 = b
B) The equation of the second ordered pair is y= -3x + 17.
<u>Final answers</u>:
- A) y = -3x - 2
- B) y = -3x + 17
