Answer:

y=-1/2x-1

Step-by-step explanation:

y=mx+b

y=-1/2x+b. This is the first part. You basically plug in the slope for m. To solve for b, you have to plug in the x and y coordinates into the equation

6=(-14)(-1/2)+b

6=7+b

-1=b

So now you have your slope and your y-intercept, plug it back into the y=mx+b format

y=-1/2x-1 would be the final answer

Answer:

y = mx+b

m represents the slope and b represents the y-intercept

since you have the slope and a point you can find here the line crosses the y-axis

y = -1/2x + b

the point (-14, 6) can be substituted into the eq for x and y

(6) = -1/2(-14)+b

6 = 7 +b (subtract 7 from both sides)

-1 = b

The line crosses the y-axis at -1

Can someone please help me solve this? I will give brainist for the person who does it correctly.

Answer:

Yes the car was speeding

Step-by-step explanation:

s = √(30fd) where

s is the speed of the car in mph
f is the coefficient of friction for the road
d is the length in feet of the skid marks

Substitute d = 41.5 and f = 0.8 into the equation:

s = √(30 x 0.8 x 41.5)

⇒ s = √(996)

⇒ s = 31.55946768...

Therefore, for these data, the speed of the car was 31.56 mph (to the nearest hundredth)

The speed limit was 30 mph, therefore the car was speeding as 31.56 > 30

Graph the line y = kx +1 if it is known that the point M belongs to it: M(1,3)

tigry1 [53]

Answer:

$M(x,y) = (1,3)$ belongs to the line $y = 2\cdot x +1$ . Please see attachment below to know the graph of the line.

Step-by-step explanation:

From Analytical Geometry we know that a line is represented by this formula:

$y=k\cdot x + b$

Where:

$x$ - Independent variable, dimensionless.

$y$ - Dependent variable, dimensionless.

$k$ - Slope, dimensionless.

$b$ - y-Intercept, dimensionless.

If we know that $b = 1$ , $x = 1$ and $y = 3$ , then we clear slope and solve the resulting expression:

$k = \frac{y-b}{x}$

$k = \frac{3-1}{1}$

$k = 2$

Then, we conclude that point $M(x,y) = (1,3)$ belongs to the line $y = 2\cdot x +1$ , whose graph is presented below.

Can you think of a situation where comparing two fractions directly is easier than converting them to decimal or percents in ord

Andrei [34K]

when you are comparing 1/2 to 3/6. this is because you know that 1/2 is equal to 3/6. You are very welcome, and thank you for the challenge.
