Answer:
y = 2x + 12
Step-by-step explanation:
Get the standard form equation into y = mx + b form.
Then, use the recipricol of the m value to get the slope for the perpendicular line.
Then, plug in the point and solve for the b value.
Work :
y = -1/2x-5/4
Perpendicular line slope : 2
y = 2x + b
-4 = 2(-8) + b
-4 = -16 + b
b = 12
y = 2x + 12
Answer:
The equation (i) is the only algebraic equations.
Step-by-step explanation:
From the given examples of equations the equation (i) is the only algebraic equations.
(i) 3.1x - 11.2 = 2.5x + 2.3.
This is an example of algebraic equation with single variable x.
(ii) ???? + ???? = 2????
This could be an equation with variable ???? but both the sides being equal they cancel each other and no equation remains.
(iii) 1/2 +1/2 = 2/4
This is not an algebraic equation since there is no variable. (Answer)
