Answer:
A, the solutions are x=3,2
Step-by-step explanation:
It's a decimal, but you can rewrite it as a fraction: -8/10 or -4/5 (simplified).

Slope Formula: 
Slope-Intercept Form: y = mx + b
- m - slope
- b - y-intercept
Step-by-step explanation:
<u>Step 1: Define</u>
y-intercept (0, 5)
Point (1, 2)
<u>Step 2: Find slope </u><em><u>m</u></em>
Simply plug in the 2 coordinates into the slope formula to find slope <em>m</em>
- Substitute [SF]:

- Subtract:

- Divide:

<u>Step 3: Write Equation</u>
<em>Plug in variables into the general form.</em>
y = -3x + 5
Y = 1
Using y = mx + c.
Compare to y = 1, y = 0x + 1 ,
We can see that the slope m = 0 and the vertical intercept, c = 1.
For the line perpendicular to y = 1
Condition for perpendicularity m₁m₂ = -1
m₁ = 0, m₂ = ?
0*m₂ = -1
m₂ = -1/0 = Negative Infinite or Infinite
Slope of line perpendicular to y = 1, is = Infinite.
