Write an equation of a line parallel to y = 5x + 4 that passes through (-1, 2)
nikitadnepr [17]

The equation of a line parallel to y = 5x + 4 that passes through (-1 , 2) is y = 5x + 7

Step-by-step explanation:

The parallel lines have:

  • Same slopes
  • Different y-intercepts

The form of the linear equation is y = mx + b, where m is the slope of the line and b is the y-intercept

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

∴ m = 5 and b = 4

∵ The two lines are parallel

∴ Their slopes are equal

∴ The slope of the parallel line = 5

- Substitute the value of the slope in the form of the equation

∴ y = 5x + b

- To find b substitute x and y in the equation by the coordinates

   of any point on the line

∵ The parallel line passes through point (-1 , 2)

∴ x = -1 and y = 2

∵ 2 = 5(-1) + b

∴ 2 = -5 + b

- Add 5 to both sides

∴ 7 = b

- Substitute the value of b in the equation

∴ y = 5x + 7

The equation of a line parallel to y = 5x + 4 that passes through (-1 , 2) is y = 5x + 7

Micayla wants the print shop to reduce the size of her painting but keep the ratio of length to width so that it will fit her fr
marissa [1.9K]

Answer:

The width of the frame must be 12 inches (15in by 12in)

Step-by-step explanation:

Given

See attachment for painting and frame

Required

Determine the dimension of the frame

To do this, we make use of the following scale ratio.

Scale = Length : Width

For the painting,

Scale = 20: 16

For the frame,

Scale = 15: w

Since she wants to maintain the same ratio; both scale must be the same.

i.e.

15 : w = 20 : 16

Express as fraction

\frac{w}{15} = \frac{16}{20}

\frac{w}{15} = 0.8

Make w the subject

w = 15 * 0.8

w = 12

<em>The width of the frame must be 12 inches i.e. 15in by 12in frame</em>

AGAIN.... HELP MEH PLZ! IF YOU'RE CORRECT YOU'LL BRAINLIEST!
Dima020 [189]

Answer:

U' = (0,2)

V' = (0,5)

W' = (-5,5)

Step-by-step explanation:

To get these, you can subtract 2 from the x-value because they are moving 2 units to the left and add 2 to the y-value because they are moving 2 units up.
