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}

galina1969 [7]

Answer:

1200 miles.

Step-by-step explanation:

Let d represent one way distance.

We have been given that a plane averaged 800 mph on a trip going​ east, but only 400 mph on the return trip.

\text{Time}=\frac{\text{Distance}}{\text{Speed}}

The time taken while going east would be \frac{d}{800}.

The time taken while returning back would be \frac{d}{400}.

Since the total flying time in both directions was 4.5 hr, so we will equate sum of both times with 4.5 as:

\frac{d}{800}+\frac{d}{400}=4.5

Make a common denominator:

\frac{d}{800}+\frac{d*2}{400*2}=4.5

\frac{d}{800}+\frac{2d}{800}=4.5

\frac{d+2d}{800}=4.5

\frac{3d}{800}=4.5

\frac{3d}{800}\times \frac{800}{3}=4.5\times \frac{800}{3}

d=1.5\times \frac{800}{1}

d=1200

Therefore, the one-way distance was 1200 miles.
