The equation Of the line is y =-3.5x-4.5
lilavasa [31]3 years ago
6 0

Answer: y = -3.5x - 4.5

suppose: the equation of the line is y = ax + b ( a ≠ 0 )

because the line passes through (-2;2.5) => 2.5 = -2a + b

the line passes though (0;-4.5) => -4.5 = b

=> b = -4.5

   2.5 = -2a + b

=> a = -3.5

    b = -4.5

=> the equation of the line is y = -3.5x - 4.5

Step-by-step explanation:

3. Given the graph below, determine whether each statement is true or false.
MaRussiya [10]

Answers:

  1. True
  2. True
  3. True
  4. False
  5. False

======================================

Explanation:

In this context, a zero is another term for x intercept or root. This is where the graph either touches or crosses the x axis. This occurs in three locations: x = -3, x = 2, and x = 0. So those are the three roots. That makes the first three statements true, while the remaining two others are false.

Side note: x = 0 doesn't always have to be involved. Its quite possible to have x = 0 not be an x intercept. The term "zero" is a bit misleading in that regard. I prefer either "root" or "x intercept" instead.
