Answer:

  a) x = -3

  b) y = (28/27)x -27

Step-by-step explanation:

a) College street has a slope of 0, so is a horizontal line. 2nd Ave is perpendicular, so is a vertical line, described by an equation of the form ...

  x = constant

For 2nd Ave to intersect the point (-3, 1), the constant must match that x-coordinate. The equation is ...

  x = -3

__

b) Since Ace Rd is perpendicular to Davidson St, its slope will be the opposite reciprocal of the slope of Davidson St. The slope of Ace Rd is ...

  m = -1/(-27/28) = 28/27

Using the point-slope equation for a line, we can model Ace Rd as ...

  y -y1 = m(x -x1)

  y -1 = (28/27)(x -27)

  y = (28/27)x -27

What is the equation of the lines -6,-4 & 4,6
Jet001 [13]
1. use the equation y -y1 = m(x-x1)
2. (-6,-4) is x1,y1 and (4,-6) is x2,y2
3. y-(-4) = m(x-(-6)
m is the gradient, 10/10, which is 1. make two negatives into a positive.
4. y+4 = x+6

therefore the equation of the lines is y = x+2

substitute the points back into the equation to double check.

6^2.6^4 plz plz plz p​
marissa [1.9K]

Answer:

6^6 = 46656

Step-by-step explanation:

I’m assuming your saying: 6^2 · 6^4, which is equivalent to 6^6 because if two numbers have the same base (in this case it’s 6), then you just add the exponents: add the exponents 2 + 4 = 6  ⇒  6^6

6^6 = 46656
