y=2x-4

Step-by-step explanation:

so we have to find perpendicular meaning the lines should form an x so exactly the opposite. The slope is -1/2 so we can change slope to 2.

Now we plug in coordinates into equation

y=2x+b

y=2(-4) +4

y=-8+4

y=-4

so we know y intercept now too

y=2x-4

where is the figure

n=9

step-by-step explanation:

7 times a number = 7n

decreased by 13 = 7n-13

same as is =

5 times the number = 5n

increased by 5 = 5n+5

7n-13 = 5n+5

2n=18

n=9
