Answer:
y = -3x + 8
Step-by-step explanation:
First, find the slope using rise/run
21/-7
= -3
Then, find the y-intercept by using the slope and by plugging in a point
5 = -3(1) + b
5 = -3 + b
8 = b
So, the equation will be:
y = -3x + 8
Parallel = same slope
Y = 5x + b
8 = 5(5) + b
8 = 25 + b
b = -17
Equation: y = 5x - 17
Based on the given parameters, the value of y is 45
<h3>How to determine the value of y?</h3>
The given parameters are
Slope = 3
Value of x = 15
The value of y is calculated as:
y = Slope * x
This gives
y = 3 * 15
Evaluate
y = 45
Hence, the value of y is 45

Answer:
x = 3/8 +/- i(√5)/8.
Step-by-step explanation:
I can't see any list by this is the solution of the equation:
x^2 - 3/4x = -1/4
x^2 - 3/4 x + 1/4 = 0
Multiply by 4 to remove the fractions:
4x^2 - 3x + 1 = 0
x = [-(-3) +/- sqrt(3)^2 - 4*4*1)] / 8
x = 3/8 +/-√ (-5) / 8
x = 3/8 +/- √5 i / 8
