Answer:
Equation of the Line: y = 1.25x + 5
Equation in Standard Form: 5x - 4y = -20
Step-by-step explanation:
y = mx + b
= 
= 
or 1.25
y = 1.25x + 5
Ax + By = C (A must be positive, and no fractions or decimals)
y = 1.25x + 5
-1.25x + y = 5
times -4
5x - 4y = -20
Hello!
x² - 4x + 6 = 9 <=>
<=> x² - 4x + 6 - 9 = 0 <=>
<=> x² - 4x - 3 = 0 <=>
<=> x = -(-4)±√(-4)²-4×1×(-3)/2×1 <=>
<=> x = 4±√16+12/2 <=>
<=> x = 4±√28/2 <=>
<=> x = 4±2√7/2 =>
=> x = 4+2√7/2 and x = 4-2√7/2 =>
=> x = 2+√7 and x = 2-√7
The equation has two solutions.
Good luck! :)
