Write an equation of a line that passes through 2,0 and is the perpendicular to the line y=-1/2x +3

9514 1404 393

  y = 2x -4

Step-by-step explanation:

The coefficient of x in the given equation is the slope of the line. A perpendicular line will have a slope that is the opposite reciprocal:

  -1/(-1/2) = 2

The point-slope form of the equation of a line can be used to find the desired equation:

  y -y1 = m(x -x1) . . . . . . line through (x1, y1) with slope m

For (x1, y1) = (2, 0) and m = 2, the equation is ...

  y -0 = 2(x -20

  y = 2x -4

let x be the money she spent so that she can earn the free t-shirt.

since, she already spent $112.49

⇒

also, as per the statement: jennifer must spend $250 or more in order to qualify for a free t-shirt at the store.

then,

we have an inequality i.,e

subtract 112.49 from both sides we get;

therefore, $137. 51 more money does jennifer need to spend so that she can earn the free t-shirt
