In the generalized slope-intercept equation of a line, the slope of the line is
xxTIMURxx [149]

Answer:

A. True

Step-by-step explanation:

A generalized slope-intercept equation of a line is of the form:

y=mx+b

Where, 'm' is the slope of the line and 'b' is the y-intercept of the line.

The slope is the rate of change of 'y' with respect to changing 'x'. The slope of a line can be positive or negative.

If 'y' increases with 'x', slope is positive. If 'y' decreases with 'x', slope is negative.

In the above equation, the term that is multiplied to 'x' is called the coefficient of 'x'. Here, 'm' is multiplied to 'x'.

Therefore, the coefficient of 'x' in the above equation is 'm'. Thus, from the generalized equation, one can conclude that the coefficient of 'x' in the equation represents the slope of the line.

Hence, the statement is TRUE.

Answer:

AO and OC

x+8 and 16-x

x+8 = 16-x

x+x= 16-8

2x= 8

x= 8/2

x=4

DO and OB

2y+13 and 5y+4

2y+13 = 5y+4

2y-5y= 4-13

-3y = -9

y= 9/3

y= 3

A mother is 30 years older than her son. Fifteen years ago the son was 1/3 of
nalin [4]

Let s be the son's age 15 yeasr ago and m the mother's age that year.

s = \dfrac{m}{3}

We also know that:

m = s+30

Plotting vallues:

s = \dfrac{m}{3}\\\\\\3s = s+30\\\\2s = 30\\\\s = 15\\\\m = 45

Remember that they were that age 15 years ago.

So their actual age is 30 and 60.

A quadrilateral has vertices A{11, -7), B(9,-4), C11,-1), and D(13,-4).
Bess [88]

Answer:

Quadrilateral ABCD is a <u>parallelogram</u>

if the vertex C( 11, -1 ) we’re shifted to the point C ( 11, 1 ), quadrilateral ABCD would be a <u>kite</u>

Step-by-step explanation:

without solving, im guessing that quad ABCD is a paralellogram (//gram)

lets test this theory

see if the slope of AB and CD, and BC and AD is the same

slope AB and CD

AB:

-7--4/11-9

=-3/2

CD:

-1--4/11-13

=3/-2

=-3/2

slope is the same

slope BC and AD

BC:

-4--1/9-11

=-3/-2

=3/2

AD:

-7--4/11-13

=-3/-2

=3/2

slope is same

because 2 pairs // sides ---> //gram

if the vertex C( 11, -1 ) we’re shifted to the point C ( 11, 1 ), quadrilateral ABCD would be a kite

hope this helps!

please mark brainliest thank you !
