the temperature of the water in Emily's fish tank was 78 degrees F on Sunday the water temperature was changed by -3 on Monday a
SpyIntel [72]

To solve this problem, let us analyze this step by step. The temperature for each day is as follows:

 

Water temperature on Sunday = 78 degrees F

Water temperature on Monday = changed by -3 degrees F

Water temperature on Tuesday = changed by 3 degrees F

 

We can see that the total change of water temperature from Sunday to Tuesday is:

-3 + 3 = 0

Therefore there is zero overall change. There the integer which represents the temperature change is “0”.

 

Since the overall change in water temperature is zero, hence the temperature on Sunday and on Tuesday is similar.

Water temperature on Tuesday = 78 degrees F

Graph the line. y=-4x+6 what the graph
Aloiza [94]
So the -4x is the M and then 6 is the B. So m is the slope and B is the y-intercept. The 6 goes on the y axis and the -4 will be how the line looks. It’ll be rise (-4) over run (1).

Help me with answering this question

Answer:

x-intercept is (-4,0) and the y-intercept is (0,-2

Step-by-step explanation:

There are 2 ways to find the y-intercept. One way is to put the equation in slope-intercept form. However, there is a more efficient way as well.

Another way to do it is to plug 0 in for x and y. The x-intercept will have the coordinate of (x,0). So to find the x-intercept you can plug in 0 for y and solve for x. To find the y-intercept do the opposite and plug 0 in for x.

So, first, plug 0 in for y

  1. x+2(0)=-4
  2. x+0=-4
  3. x=-4

Then plug in 0 for x

  1. 0+2y=-4
  2. 2y=-4
  3. y=-2

Therefore, the x-intercept is (-4,0) and the y-intercept is (0,-2).
