What is the equation of the line that passes through (-6,-6) and (12,9)?

Answers

Answer 1

Answer: The correct answer for the question that is being presented above is this one:

(1) Get the slope (m)
m = (y1 - y2) / (x1 - x2)
m = (-6 - 9) / (-6 - 12)
m = -15 / -18
m = 5/6

(2) Get the x-intercept (b)
y = mx + b
-6 = (5/6)(-6) + b
-6 = -5 + b
b = -1

(3) Form the equation
y = mx + b
y = (5/6)x -1

So the equation is y = (5/6) x - 1.

Describe the meaning of the y-intercept

Answers

Answer:

Step-by-step explanation:

In the equation of a straight line (when the equation is written as "y = mx + b"), the slope is the number "m" that is multiplied on the x, and "b" is the y-intercept (that is, the point where the line crosses the vertical y-axis).

Answer:

y-value at intercept = f(0), the value of the function when x = 0

Step-by-step explanation:

The "y-intercept" of a graph (any graph, not just a straight line) is the y-value obtained when x = 0. In other words, the y-intercept is the point at which the graph crosses the y-axis (whose equation is x = 0). Very often the y-intercept represents the initial (beginning) value of functions whose domains include [0, +infinity).

Help would be nice :p *pls don't leave this qestion.....I will cry :|*Which is the best description of the equivalency of the two expressions?

Expression 1
5 x squared minus 2 x minus 4 + 6 x + 3
Expression 2
6 x squared minus 6 x + 6 minus x squared + 10 x minus 7

A.) The two expressions are not equivalent because when x = 2, the two expressions do not have the same value.

b.)The two expressions are not equivalent because when they are simplified, they do not have the same coefficients for the x squared and x terms.

c.) They are equivalent because the sum of the constants is the same in both expressions.

D.) They are equivalent because when x = 2, the two expressions have the same value.

Fernando's family traveled 272 miles on a road trip last weekend. They drove for four hours. What was the rate at which Fernando's family traveled? Write and solve a multiplication equasion.

Answers

Total distance traveled by Fernando's family = 272 miles
Time taken to travel the distance of 272 miles = 4 hours
Then we can say that
The distance traveled by Fernando's family in 4 hours = 272 miles
So
The distance traveled by
Fernando's family in 1 hour = (272/4) * 1 miles
= 68 miles
From the above deduction we can easily conclude that Fernando's family traveled at a rate of 68 miles per hour. I hope to have helped you.
