The formula to find the slope of a line is m=(y2-y1)/(x2-x1). In this question: x1=3, x2=2, y1=5, and y2=1. Plug in and solve:
(1-5)/(2-3)=-4/-1=4=m
Slope-intercept form follows the format: y=mx+b, where m is the slope and b is the y-intercept. We calculated m to be 4, so the equation reads:
y=4x+b
To solve for b, you can select one of the ordered pairs (we'll use (2,1)), plug them in for x and y, and solve for b:
1=4(2)+b
1=8+b
-7=b
The equation is y=4x-7.
Hope this helps!!
Answer:
6
Step-by-step explanation:
60/6 = 10
6/6 = 1
The compound inequality that shows the range of number is:
<u><em>Explanation</em></u>
Isabella is thinking of a number .
Given that, 6 less than 6 times her number is between 24 and 48.
So, 6 less than 6 times the number means:
So, the inequality will be....
<em>That means, the number that Isabella might be thinking of will be in between 5 and 9. </em>
So, the compound inequality that shows the range of number is:
Answer:
-18
Step-by-step explanation:
So you have to always add the ones with parentheses. I added (-6) + (-6) and I get the answer -12. Last but not least I add -12 + -6 to get -18
