Slope-intercept form is y = mx + b, where m is the slope and b is the y-intercept.
The first step is to find the slope using the provided coordinates (-2, 6) and (2, 14). We can do that using the y1 - y2 / x1 - x2, like so:
6 - 14 / -2 - 2
-8 / -4
2
The slope is two, so we immediately know the answer is either A or B.
Now, plot the two points on graphing paper and determine where the line intersects the y-axis to find the y-intercept...
My graph shows the line intersecting the y-axis at 10, therefore the correct answer is:
y = 2x + 10
The first one is D
The second one is true
Answer:
A
Step-by-step explanation:
Answer: 2
Step-by-step explanation:
subtract the lowest number from the highest
4-2=2
Solution:
<u>Note that:</u>
- Percentage formula: x/100 × y = x% of y
<u>Use the formula to solve 20% of 180.</u>
- x/100 × y = x% of y
- => 20/100 × 180
- => 1/5 × 180
- => 36
20% of 180 is <u>36.</u>
