Answer:
y - 9 = -5(x + 4)
General Formulas and Concepts:
<u>Algebra I</u>
Point-Slope Form: y - y₁ = m(x - x₁)
- x₁ - x coordinate
- y₁ - y coordinate
- m - slope
Step-by-step explanation:
<u>Step 1: Define</u>
Slope <em>m</em> = -5
Coordinate (-4, 9) → x₁ = -4, y₁ = 9
<u>Step 2: Write Function</u>
<em>Substitute into general form.</em>
y - 9 = -5(x - -4)
y - 9 = -5(x + 4)

Answer:
x=56.388....
Step-by-step explanation:
16x-8+2x=1007
18x-8=1007
18x=1007+8
18x=1015
x=1015/18
x=56.38
(-2/3, 2)
Solve for the first variable in one of the equations, then substitute the result into the other equation.
So 4*10^7 is _ times greater then 4*10^3
So, 4000, 40000000
So 10000 times greater
