To start, the equation has to be converted to slope-intercept form, or y=mx+b. Start by subtracting x from both sides; x-x+2y=4, 2y=4-x. Switch 4 and -x around to conform to the formula; 2y=-x+4. Then divide by 2 to isolate y; y=-\frac{1}{2}x+2. This is the final equation. Because the slope of a line perpendicular is always the opposite reciprocal (i.e. The opposite reciprocal of 4 is -\frac{1}{4}, the opposite reciprocal of -\frac{1}{5} is 5) the opposite reciprocal of -\frac{1}{2}  is 2. So the equation of the line is y=2x, and the answer is A.

Question 14
Reil [10]

Answer:

The system of equations has a one unique solution

Step-by-step explanation:

To quickly determine the number of solutions of a linear system of equations, we need to express each of the equations in slope-intercept form, so we can compare their slopes, and decide:

1) if they intersect at a unique point (when the slopes are different) thus giving a one solution, or

2) if the slopes have the exact  same value giving parallel lines (with no intersections, and the y-intercept is different so there is no solution), or

3) if there is an infinite number of solutions (both lines are exactly the same, that is same slope and same y-intercept)

So we write them in slope -intercept form:

First equation:

6x+y=-1\\y=-6x-1

second equation:

-6x-4y=4\\-6x=4y+4\\-6x-4=4y\\y=-\frac{3}{2} x-1

So we see that their slopes are different (for the first one slope = -6, and for the second one slope= -3/2) and then the lines must intercept in a one unique point. Therefore the system of equations has a one unique solution.
