Answer:y= -9x-25
Step-by-step explanation: Write the slope-intercept form of an equation of the line with slope -9 and passes through the point (-2, -7).
--------
Form:: y = mx + b
Solve for "b"::
-7 = -9*-2 + b
-7 = 18 + b
b = -25
-----
Equation:
y = -9x - 25
---------------

-----------
point slope formula
y-y1=m(x-x1)
y+7= -9(x+2). Notice that we are subtracting a negative, so we have to add.
y+7=-9x-18
y= -9x-25

Answer:
1.6* 10^5
Step-by-step explanation:
1. Move the decimal place to the left to make a number from 1 to 10.
2. Find the exponent, that is the number of times you moved the decimal.
3.Then put the number in scientific notation.
Answer:
D
Step-by-step explanation:
Given
x² - 7x + 12
Consider the factors of the constant term (+ 12) which sum to give the coefficient of the x- term (- 7)
The factors are - 4 and - 3, since
- 4 × - 3 = + 12 and - 4 - 3 = - 7, thus
x² - 7x + 12 = (x - 4)(x - 3) ← in factored form → D
