Write an equation of the line that passes through (2,-4) and (0,-4)
Arte-miy333 [17]

y = mx + b

To find the slope(m), you use the slope formula:

m = \frac{y_{2}-y_{1}}{x_{2}-x_{1}}

You plug in the points into the equation.

m = \frac{-4 - (-4)}{0 - 2}

m = \frac{-4+4}{0-2} = \frac{0}{-2} =0

The slope is 0

y = 0x + b

Any number multiplied by 0 is 0. So:

y = b

To find b, you plug in the y value of either of the points.

-4 = b

Your equation is:

y = -4 (This is a horizontal line)

Shop only had 2 types of stamps left using
saveliy_v [14]

Answer:

  {3¢, 28¢} or {4¢, 19¢} or {7¢, 10¢}

Step-by-step explanation:

54 = 1×54 = 2×27 = 3×18 = 6×9

Possible values of the stamps are 1 more than the values of a pair of factors. Of course, a 2¢ and 55¢ stamp will not permit paying 54¢ in postage, so that combination won't work. However, other pairs that will work are ...

  • 3¢ and 28¢
  • 4¢ and 19¢
  • 7¢ and 10¢

Which of the following is an equation of the line that passes through the point (2, 2) and is parallel to the graph of the equat
pickupchik [31]

Answer:

B

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

y = 3x - 1 ← is in slope- intercept form

with slope m = 3

Parallel lines have equal slopes, thus

y = 3x + c ← is the partial equation of the parallel line

To find c substitute (2, 2) into the partial equation

2 = 6 + c ⇒ c = 2 - 6 = - 4

y = 3x - 4 → B
