What is the slope-intercept form of the equation of the line perpendicular to y = -x + 10 and passing throught the point (-2,7)?
notka56 [123]

Answer:

The slope-intercept form equation of the line perpendicular to y =  -\frac{1}{2} x + 10 and passes through point (-2, 7) is y = 2x + 11 ⇒ Not in the choices

Step-by-step explanation:

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

  • m is the slope
  • b is the y-intercept

The product of the slopes of the perpendicular lines is -1, if the slope of one is m, then the slope of the other is -\frac{1}{m}

  • To find the slope of the perpendicular line to a given line reciprocal the slope of the given line and change its sign

∵ The equation of the given line is y = -\frac{1}{2} x + 10

→ Compare it with the form of the equation above

∴ m =  -\frac{1}{2}

→ Reciprocal it and change its sign to get the slope of the ⊥ line

∴ m⊥ = 2

→ Substitute in the form of the equation above

∴ y = 2x + b

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

   a point on the line

∵ The line passes through the point (-2, 7)

∴ x = -2 and y = 7

∵ 7 = 2(-2) + b

∴ 7 = -4 + b

→ Add 4 to both sides to find b

∵ 7 + 4 = -4 + 4 + b

∴ 11 = b

→ Substitute it in the equation

∴ y = 2x + 11

The slope-intercept form equation of the line perpendicular to y =  -\frac{1}{2} x + 10 and passes through point (-2, 7) is y = 2x + 11

<u><em>Note:</em></u> The answer is not in the choices

Answer:

y = 9/10x - 7/5

Step-by-step explanation:

Slope = 9/10

Point (6,4)

y-intercept = 4 - (9/10)(6) = 4 - 54/10

= - 7/5

Y_Kistochka [10]

Answer:The answer are the red card(The second), A dependent event is an event that relies on another event to happen first.

Since he keep his first took red card,his probability to get another red card became lower,therefore it effects on what card he will take next.

the third one doesn't called a dependent event because it's a Dice,so the probability still the same

The fourth one doesn't count to,since he return back the marble.
