Answer: 4
The given line has a slope of -1/4 as this is the number in front of the x. The general equation y = mx+b has m as the slope. So m = -1/4 is given
Flip the sign to get -1/4 turn into +1/4 or just 1/4
Then flip the fraction (aka reciprocal) to go from 1/4 to 4/1 and that simplifies to 4.
Multiplying the original slope (-1/4) and the perpendicular slope (4) will result in -1.

Step-by-step explanation:
I think the answer of this question is number b. quadratic
Answer:
None of the graphs of the equations pass through M(−10, 15).
Step-by-step explanation:
We are given the function 
.
It is given that the point B lies on the graph of the given function.
1. B(2, −3)
That is, x= 2 and y= -3
So, y= kx ⇒ -3 = 2k ⇒ 
Thus, the function is 
2. 
i.e. 
That is, 
and y= -2
So, y= kx ⇒ 
⇒ 
⇒ 
Thus, the function is 
From the graph plotted below, we get that,
None of the graphs of the equations pass through M(−10, 15).
Part A
The 4 angles of a quadrilateral add to 360. To see why, draw a line from A to C. The quadrilateral is divided into 2 triangles. All triangles have interior angles that add to 180. Since there are 2 such triangles, the total is 2*180 = 360. Write a summation for the 4 angles.
2x + 3x + x + 90 = 360 Combine like terms on the left
6x + 90 = 360 Subtract 90 from both sides.
6x + 90 - 90 = 360 - 90 Collect like terms
6x = 270 Divide both sides by 6
6x/6 = 270/6 Do the division
x = 45
Part B
Since x = 45 then2x = 90
Since <A and <B = 90 And since they are equal interior angles and
both are 90 degrees,the lines are parallel.
