Answer:

y=2x+1

Step-by-step explanation:

step 1

Write an equation in point-slope of the line passing through point A and parallel to line B

y-y1=m(x-x1)

Remember that

If two lines are parallel, then their slopes are equal

In this problem the slope of the given line is m=2

That means

The slope of the parallel line is also m=2

we have

m=2\\point\ A(1,3)

substitute

y-3=2(x-1)

step 2

Convert to slope intercept form

y=mx+b

we have

y-3=2(x-1)

isolate the variable y

y=2x-2+3

y=2x+1

write the equation in slope intercept form of the line that passes through -1, 11 and is parallel to the graph of y = -8x + 3
lawyer [7]
<h2>Answer: The line from the question [ y = -8x + 3 ] passes through the point ( -1, 11 ). </h2>

<h3 /><h3>Step-by-step explanation: </h3>

<u>Find the slope of the parallel line</u>

When two lines are parallel, they have the same slope.

                 ⇒  if the slope of this line = - 8

                      then the slope of the parallel line (m) = - 8

<u>Determine the equation</u>

We can now use the point-slope form (y - y₁) = m(x - x₁)) to write the equation for this line:  

                               ⇒  y - 11  =  - 8 (x - (-1))                                

                                ∴  y - 11  = - 8 (x + 1)

We can also write the equation in the slope-intercept form by making y the subject of the equation and expanding the bracket to simplify:

                      since   y - 11  = - 8 (x + 1)

                                        y  = - 8 x  + 3

The line from the question [ y = -8x + 3 ] passes through the point ( -1, 11 ).

Write a function rule that gives the total cost c(p) of pounds of sugar if each pound cost $.59
aliina [53]
Answer: c(p) = 0.59*p

All we do is multiply the price per pound (0.59) by the number of pounds (p). In this case, we don't know how many pounds there are. So we leave p as is. If for instance, we had 10 pounds, then we'd replace p with 10. The variable is simply a placeholder for the unknown number.
