Answer question 11 and 12

Mathematics

Darya [45]2 years ago

Answer:

11.  y = -2x - 4.

12.  y = x - 5

Step-by-step explanation:

11. the given points on the line are ((-2, 0) and (0, -4)

The slope of the line

=  difference in y values / corresponding difference in x values

= ( - 4 - 0) / 0 - (-2))

= -4 / 2

= -2.

The general form of a straight line is y = mx + c where m = the slope and c = y value of the intercept on the y-axis.

So  the equation is:

y = -2x - 4.

12.

The points are (1, -4) and (3, -2).

The slope is    (-2 - (-4)) / (3 - 1)

=  2/2

= 1.

So the equation is  

y = 1x + c

We find c by plugging in the point (1, -4):

-4 = 1 + c

c = -4 - 1

c = -5.

The equation is y = x - 5.

Which representation has a constant of variation of -2.5
Neporo4naja [7]

Answer:

See explanation

Step-by-step explanation:

The constant of variation is found using the slope formula:

\frac{y_2-y_1}{x_2-x_1}

The given relation is

X : -2 , -3, -4, -5  

Y : -5, -7.5,-10,-12.5

We can use any two ordered pair to find the constant of variation.

Using (-2,-5) and (-3,-7.5), we have

m=\frac{-7.5--5}{-3--2} =\frac{-2.5}{-1} =2.5

The constant of variation is 2.5

We need to repeat this for all the options to identify the one with -2.5 as slope.

unfortunately, you did not provide the remaining options.
