Helpppppppppppppppp ill mark you brainlist write in y=mx+b form

Sholpan [36]

Answer:

The equation of the line in slope-intercept form is:

$y\:=\:\frac{-10}{7}x-\frac{45}{7}$

Step-by-step explanation:

Given the points

(-8, 5)

(-1, -5)

Finding the slope

$\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}$

$\left(x_1,\:y_1\right)=\left(-8,\:5\right),\:\left(x_2,\:y_2\right)=\left(-1,\:-5\right)$

$m=\frac{-5-5}{-1-\left(-8\right)}$

$m=-\frac{10}{7}$

We know the slope-intercept form of the line equation is

$y = mx+b$

where m is the slope and b is the y-intercept

substituting m = -10/7 and (-8, 5) in the slope-intercept form to determine the y-intercept

$5\:=\:\frac{-10}{7}\left(-8\right)+b$

$\frac{80}{7}+b=5$

$b=-\frac{45}{7}$

now substituting m = -10/7 and b = -45/7 in the slope-intercept form

$y = mx+b$

$y\:=\:\frac{-10}{7}x+\left(-\frac{45}{7}\right)$

$y\:=\:\frac{-10}{7}x-\frac{45}{7}$

Thus, the equation of the line in slope-intercept form is:

$y\:=\:\frac{-10}{7}x-\frac{45}{7}$

Kaitlyh is mowing her lawn. The lawn has an area of 5,625 square feet. She can

sergiy2304 [10]

Answer:

After 5 minutes Kaitlyn have to mow 5,250 square feet of lawn.

Step-by-step explanation:

We are given the following in the question:

Total area of lawn = 5,625 square feet

Rate of mowing lawn = 75 square feet each minute

Area of lawn mowed in 5 minutes =

$=\text{Rate of mowing lawn}\times \text{Time}\\=75\times 5\\=375\text{ square feet}$

Square feet does Kaitlyn still have to mow after 5 minutes

$=\text{Area of lawn - Area of lawn mowed in 5 minutes}\\=5625-375\\=5250\text{ square feet}$

Thus, after 5 minutes Kaitlyn have to mow 5,250 square feet of lawn.
