Equation in slope-intercept form is y = 2x - 6
Step-by-step explanation:
- Step 1: Given slope of the line, m = 2. Form an equation y = mx + b
⇒ y = 2x + b ---- (1)
- Step 2: The line passes through the point (4,2). So it will satisfy the equation. Find b by substituting x = 4 and y = 2.
⇒ 2 = 2 × 4 + b = 8 + b
⇒ b = -6
- Step 3: Form the slope-intercept equation.
⇒ y = 2x - 6
Answer:
- gradient is 4.
- y-intercept is -5.
- No.
Step-by-step explanation:
1. In order to find the gradient of equation, you have to make it into slope-form equation y = mx + b :
So m represents gradient. In this question, m is 4.
2. Make it into slope-form equation :
In this question, y-intercept is b which is -5.
3. You have to substitute x-coodinate into the equation to see whether it is equal to y-coordinate :
The types of radiation are
Alpha
Beta
Gamma
Alpha radiation is the energy carried by fast moving helium atoms.
Beta radiation is the energy of electrons released from atoms.
Gamma radiation is the energy released by radioactive or unstable atoms.

Answer:
He had hiked 3/12 of a mile so the answer is 8/12 of a mile
Step-by-step explanation:
You need to make 1/4 into twelves by multiplying both sides by 3 to get 3/12.
You take that and subtract it from the total distance. 11/12 - 3/12 = 8/12
Answer:
4=x
Step-by-step explanation:
y=-x+4
y=2x-8
-x+4=2x-8
+x +x
4=3x-8
+8 +8
12=3x
/3 /3
4=x
