We have the following equation from the line
We must remember that the equation of the line is expressed in the form y=mx+b, where a represents the slope of the line.
Since we are standing a line parallel to the line described in the previous equation, we must ensure that their slopes are exactly the same, so when identifying the slope of the equation, this same slope is used for a completely parallel line.
In conclusion, the slope of the line that is parallel to the line y = 2x + 5 is:
Answer:
3.69 (rounded)
Step-by-step explanation:
Substitute x for "a number".
New equation: x(x + 2) = 21
Distribute and combine to form a single equation: x^2 + 2x - 21 = 0
Use quadratic formula, factoring, or graphing to get all possible answers.
Quadratic formula: , where A = x^2 coefficient, B = x coefficient, and C = constant.
-5.69, 3.69
Eliminate an incorrect answer that does not line up with the above equation.
3.69
