20 points me ! graph the following lines and write the equation in slope-intercept form. through the points (4,2) and (3,1).

y= x-2

To draw this on the graph use the y-intercept to count the number of units you need to move up or down along the y axis. Then to plot the second point using the slope value to determine how many units to move up or down from the y-intercept point in this case it is 1. join the points to draw the line of slope intercept on the graph

Solution:

Find the slope in order to find the line of equation

m= y2-y1/x2-x1

Take both the coordinates and name it A (4,2) B(3,1) for convenience

m= 1-2/3-4

m=-1/-1

m=1 (slope)

Now find the y intercept using the equation below

y=mx+ b

where

y = y coordinate

m= slope

x= x coordinate

b= y intercept

SO

Note: use any of the coordinate the answer would be the same in either case

I will be using the coordinate (4,2)

y=mx+b

2=(1)(4)+b

2-4=b

-2=b

So the equation is

y= x-2

answer: a

step-by-step explanation:

"it's not the heat, it's the humidity".   that's a partly valid phrase you may have heard in the summer, but it's actually both.   the heat index, also known as the apparent temperature, is what the temperature feels like to the human body when relative humidity is combined with the air temperature.   this has important considerations for the human body's comfort.   when the body gets too hot, it begins to perspire or sweat to cool itself off.   if the perspiration is not able to evaporate, the body cannot regulate its temperature.   evaporation is a cooling process.   when perspiration is evaporated off the body, it effectively reduces the body's temperature.   when the atmospheric moisture content (i.e. relative humidity) is high, the rate of perspiration from the body decreases.   in other words, the human body feels warmer in humid conditions.   the opposite is true when the relative humidity decreases because the rate of perspiration increases.   the body actually feels cooler in arid conditions.   there is direct relationship between the air temperature and relative humidity and the heat index, meaning as the air temperature and relative humidity increase (decrease), the heat index increases (decreases).
