Which of the following represents the equation of the line passing through (-4,5)
Sergio [31]

Answer:

Answer: y=2x+13.

Step-by-step explanation:

Your input: find the equation of the line perpendicular to the line y=5/2−x/2 passing through the point (−4,5).

The equation of the line in the slope-intercept form is y=5/2−x/2.

The slope of the perpendicular line is negative inverse: m=2.

So, the equation of the perpendicular line is y=2x+a.

To find a, we use the fact that the line should pass through the given point: 5=(2)⋅(−4)+a.

Thus, a=13.

Therefore, the equation of the line is y=2x+13.

Answer: y=2x+13.

Which number should each side of the equation 3/4 = 9 be multiplied by to produce the equivalent equation of x = 12?
Tema [17]
You need to multiply both sides of the equation by the reciprocal of 3/4. The reciprocal is 4/3 and  4/3 multiplied by 9 = 12. So x = 12 because a number times the reciprocal is one.

Find the slope of this graph, thanks
Anarel [89]

Slope  =  (change in 'y') / (change in 'x')

If you find two points where the line goes through the corners of boxes,
then count up the 'y' boxes and the 'x' boxes between those two points,
you'll find that the line rises 3 y-boxes for each x-box.

The slope of the line is  3 .
