Answer:

Refer to the graph with Slope(m) = 4 and Y-Intercept

=

−

8

Explanation:

y

=

m

x

+

b

is the equation of a straight line usually written this way, where

m

represents the Slope ( or Gradient ) and

b

the Y-Intercept. It is also in Slope-Intercept Form.

Also,

m

=

r

i

s

e

r

u

n

or ( Change in y)

/

(Change in x)

We need to graph

y

=

4

x

−

8

We observe that it is already in Slope-Intercept Form.

Hence, Slope =

m

=

4

Y-Intercept

=

(

−

8

)

Go to the graph and plot the point the point

(

0

,

−

8

)

on the y-axis.

Then rise 4 and run 1. Plot the point

(

1

,

−

4

)

Then again "rise 4" and then "run" 1. Plot the point

(

2

,

0

)

Join all these points on the graph and you will find a straight line. graph{4x - 8 [-19.75, 20.25, -14.88, 5.12]}

Also refer to an additional graph available with my suggested solution with points plotted.

Hope this helps.

Write an equation of a line that passes through the points (1, 7) and (5, 19) . Give the final form in slope intercept form. (Pl
Alinara [238K]

Answer:

y = 3x + 4

Step-by-step explanation:

slope = (y2 -y1)/(x2 - x1)

y2 = 19

y1 = 7

x2 = 5

x1 = 1

Slope = (19 - 7)/(5 - 1)

slope = 12 / 4

slope = 3

So far what you have is

y = 3x + b                      To solve for b, use either of the two points.

x = 1

y = 7

7 = 3(1) + b

7 = 3 + b

b = 4

The final equation is

y = 3x + 4                    

We should check that with the other  point

x = 5                  Find y

y = 3(5) + 4

y = 15 + 4

y = 19              Ans it checks.

They take 5 days to drive 679 miles to Seattle, how many miles will they drive each day?
Kisachek [45]

If they take 5 days to drive 679 miles to Seattle. Then the number of miles that they drive each day will be 135.8 miles per day.

<h3>What is speed?</h3>

The distance covered by the particle or the body in an hour is called speed. It is a scalar quantity. It is the ratio of distance to time.

We know that the speed formula

Speed = Distance/Time

They take 5 days to drive 679 miles to Seattle.

Then the number of miles that they drive each day will be

→ 679 / 5

→ 135.8 miles per day.

More about the speed link is given below.

Evaluate the expression(-3.8)+0+y for the given values of y.
11111nata11111 [884]

Answer:

y = -3.3 then  -7.1

y = -7.1 then  -10.9

y = -2.6 then -6.4

y = 1 then -2.8

y = 4.2 then 0.4

Step-by-step explanation:

(-3.8)+0+y can be simplified to -3.8 + y. Evaluate each value for y by substituting it into the expression and solving.

y = -3.3 then -3.8 + -3.3 = -7.1

y = -7.1 then -3.8 + -7.1 = -10.9

y = -2.6 then -3.8 + -2.6 = -6.4

y = 1 then -3.8 + 1 = -2.8

y = 4.2 then -3.8 + 4.2 = 0.4
