Komok [63]2 years ago

Answer:

y=-\frac{1}{2}x-8

Step-by-step explanation:

(-4,-6)(-2,-7)

Step 1. Find the slope (by using the slope-formula)

m = slope

m=\frac{y_2-y_1}{x_2-x_1}

m=\frac{-7--6}{-2--4}

m=\frac{-1}{2}

m=-\frac{1}{2}

Step 2. Create the equation of a line that has a slope of -\frac{1}{2}

y=-\frac{1}{2} x+b

Step 3. Find the y-intercept

To do this, use any of the two points and substitute their x and y values

y=-\frac{1}{2}x+b

point: (-2,-7)

(-7)=-\frac{1}{2}(-2)+b

(-7)=1+b

b=-7-1

b=-8

Step 4. Write the equation in Slope-intercept form

y=mx+b

y=-\frac{1}{2} x-8

snow_lady [41]

Answer:

542 minutes

Step-by-step explanation:

currently our mean is =530

i got that by adding all the number out which equal too =2,650

and divide it by how many number there are which is 5

2,650/5=530

After some trial and error i found it

so you add 494+690+502+478+486+542=3,192

3,192/6=532

and that was our goal

so the 6th month she talked on the phone for 542 minutes

Which statement is true about the line represented on the equation y + 7 = -3 (x - 2/9) ?
Zarrin [17]

<u>ANSWER</u>

The point (\frac{2}{9},-7) lies on the straight line y+7=-3(x-\frac{2}{9})

<u>EXPLANATION</u>

The given line is y+7=-3(x-\frac{2}{9}). It can be observed that the given straight line is in the point-slope form.

We can rewrite the equation in the point-slope form to obtain,


y--7=-3(x-\frac{2}{9}).


When we compare this to the general point-slope form, which given by the formula;

y-y_1=m(x-x_1),

We can observe that,

x_1=\frac{2}{9} and y_1=-7.


Hence the point, (x_1,y_1)=(\frac{2}{9},-7) lies on y+7=-3(x-\frac{2}{9})
