Steps to find the equation
1. Find the slope
2. Insert slope into the general equation
3. Find y-intercept
4. Insert -intercept into the equation found in step 2
And you get the equation of the line
----------------------------------------------------------------------------------------------
Find the slope
----------------------------------------------------------------------------------------------
2y - x = 4
----------------------------------------------------------------------------------------------
Rewrite into the form y = mx + c
----------------------------------------------------------------------------------------------
2y = x + 4
y = 1/2 x + 2
Slope = 1/2
Perpendicular slope = -2 (negative reciprocal)
----------------------------------------------------------------------------------------------
Insert slope into the equation
----------------------------------------------------------------------------------------------
y = mx + c
y = -2x + c
----------------------------------------------------------------------------------------------
Find y-intercept
----------------------------------------------------------------------------------------------
y = -2x + c
At point (1, 2)
2 = -2(1) + c
2 = -2 + c
c = 4
----------------------------------------------------------------------------------------------
Insert y-intercept into the equation y = -2x + c
----------------------------------------------------------------------------------------------
y = -2x + 4
----------------------------------------------------------------------------------------------
Answer: y = -2x + 4

7/18 is the simplified answer.
Answer: y = 2x - 13
Explanation:
Slope intercept form: y = mx + c where m is the gradient/slope (how steep the line is) and c is the y intercept ( the point where the line crosses the y axis)
It states parallel, so you know that the gradient has to be the same (they need to be "steep" at the same rate to be parallel)
Substitute the numbers in:
y = mx + c
-5 = 2(4) + c
-5 = 8 + c
c = -8-5
c = -13
With this, rewrite the equation:
y = 2x - 13
Answer:
x=4
Step-by-step explanation:
take the cube root of both sides
(4x4x4= 64)
