Answer:

(0,-2)

Step-by-step explanation:

First we find the equation of the line passes through (-3,-5) and (7,5).

The slope of the line is

m=\frac{5-(-5)}{7-(-3)}\\=\frac{10}{10}\\=1

So by the point slope formula the equation of the line is

y-5=1(x-7)\\y=x-7+5\\y=x-2

When x=0 we have y=0-2=-2.

Therefore the line joining the two points cuts the y-axis at (0,-2).

Answer:

a) x =  7.5

b) x = 1

Step-by-step explanation:

a)

  • (4x - 1)/2 = x + 7
  • 4x - 1 = 2(x + 7)
  • 4x - 1 = 2x + 14
  • 2x = 15
  • x = 15/2 or 7.5

b)

  • 3x + 2 = (2x +13)/3
  • 3(3x + 2) = 2x + 13
  • 9x + 6 = 2x +13
  • 7x = 7
  • x = 1

Which linear function represents the line given by the point-slope equation
Setler79 [48]

Rewrite the given y – 8 = 1/2(x – 4), replacing "y" with "f(x)."


Then f(x) – 8 = 1/2(x – 4)


Multiply all 3 terms by 2 to eliminate the fraction (1/2):


2f(x) = 16 + x - 4


Combine like terms: 2f(x) = x + 12

x + 12

Divide both sides by 2: f(x) = -----------

2


Note that this is equivalent to f(x) = (1/2)x + 6. Important: Use parentheses as indicated.
