Answer:
2x - y = 0
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = 2x - 1 ← is in slope- intercept form
with slope m = 2
Parallel lines have equal slopes, thus
y = 2x + c ← is the partial equation
To find c substitute (1, 2) into the partial equation
2 = 2 + c ⇒ c = 2 - 2 = 0
y = 2x ← equation in slope- intercept form
Subtract y from both sides
0 = 2x - y , that is
2x - y = 0 ← equation in standard form

Step-by-step explanation:
<u>Step 1: Define</u>
2(k - 5) + 3k = k + 6
<u>Step 2: Solve for </u><em><u>k</u></em>
- Distribute 2: 2k - 10 + 3k = k + 6
- Combine like terms: 5k - 10 = k + 6
- Subtract <em>k</em> on both sides: 4k - 10 = 6
- Add 10 on both sides: 4k = 16
- Divide 4 on both sides: k = 4
<u>Step 3: Check</u>
<em>Plug in k into the original equation to verify it's a solution.</em>
- Substitute in <em>k</em>: 2(4 - 5) + 3(4) = 4 + 6
- (Parenthesis) Subtract: 2(-1) + 3(4) = 4 + 6
- Multiply: -2 + 12 = 4 + 6
- Add: 10 = 10
Here we see that 10 does indeed equal 10.
∴ k = 4 is the solution to the equation.
