Answer:

Step-by-step explanation:
The slope of a line that is perpendicular to another will have an opposite-reciprocal slope. So, if the slope was -2, then the perpendicular slope would be
.

This is written in slope-intercept form:

m is the slope and b is the y-intercept. Find the opposite-reciprocal of the slope, -5:

Now we need to find the y-intercept. For this, substitute the given points for its appropriate value:

Solve for b:
Simplify multiplication:

Insert:

Subtract b from both sides:

Subtract 3 from both sides:

Simplify subtraction:

Insert:

Multiply both sides by - 1 to simplify b (it can be seen as -1b):

Insert:

:Done
I believe it would be b= -264
(I’m not 100% sure though so you might wanna check)
So what you would need to add to get -6 is -5-1 then your answer would be -6 hope this helps!
Answer:
90 units²
Step-by-step explanation:
The rectangular figure is 10 units wide (from -4 to +6) and 9 units high (from -4 to +5), so its area is 10·9 = 90 square units.
The answer is C), 834, 834.19, 834.2, 834.29
I know this is late, but I hope it was helpful!
