Write an equation of a line parallel to y = 5x + 4 that passes through (-1, 2)

Mathematics

5 0

Answer:

y=5x+7

Step-by-step explanation:

step 1

Find the slope of the line parallel to the given line

we know that

If two lines are parallel, then their slopes are equal

The equation of the given line is y=5x+4

The slope of the given line is m=5

so

The slope of the line parallel to the given line is also m=5

step 2

Find the equation of the line parallel to the given line

The equation of the line in point slope form is

y-y1=m(x-x1)

we have

m=5

point\ (-1,2)

substitute

y-2=5(x+1)

step 3

Convert to slope intercept form

Isolate the variable y

y-2=5x+5

y=5x+5+2

y=5x+7

mr Goodwill [35]

The options seem a bit mis-formatted but here is the way p is computed:

the decrease is 2000-1600

and it is relative to: 2000  (2003 attendance)

so p=100 \frac{2000-1600}{2000} = 100 \frac{400}{2000}

and so that aligns with your Option A. Options B, C, D look incorrect for sure.

Find parametric equations and symmetric equations for the line of intersection of the given planes. x + y + z = 5, x + z = 0
oee [108]

The next set is the parametric equations of the same line .

x = t, y = 5 and z = -t .

What is the meaning of parametric and non parametric?

  • The assumptions behind parametric statistics relate to the population's distribution from which the sample was drawn.
  • Since no presumptions are made while using nonparametric statistics, data can be gathered from samples that do not fit any particular distribution.

x + y + z = 5, x + z = 0

the line satisfies

x + z = 0 , y = 5

thus

x = t, y = 5 and z = -t .

the first one is technically already the symmetric equations of the line.

thus:

x = -z ; y = 5

the next set is the parametric equations of the same line .

x = t, y = 5 and z = -t .
