Find the slope intercept equation of the line containing (2, -3) and having slope m= 4

Mathematics
1 answer:
erica [24]3 years ago
5 0

The slope-intercept form:

y=mx+b

m - slope

b - y-intercept

We have the slope m = 4. Substitute:

y=4x+b

Put the coordinates of the point (2, -3) to the equation of a line:

-3=4(2)+b

-3=8+b       <em>subtract 8 from both sides</em>

-11=b\to b=-11

<h3>Answer: y = 4x - 11</h3>

Answer:

X ≥ 59.50

Step-by-step explanation:

So to begin, your equation would need to solve for x. X has to be greater than or equal to the minimum amount each player needs to raise for the uniforms. To find how much money they need to raise subtract $224.36 from $759.84 to get $535.48. Divided $535.48 by 9 players to see the minimum amount they each need to contribute. You should get $59.50 roughly. So each player would need to raise greater than or equal to $59.50.

Hope this helps!

What is<br> The equation of the line that passes through the points (5,-1) and (4,-5)
Murljashka [212]

For this case we have that by definition, the equation of the line in the slope-intersection form is given by:

y = mx + b

Where:

m: It is the slope of the line

b: It is the cut-off point with the y axis

We have two points through which the line passes:

(x_ {1}, y_ {1}) :( 5, -1)\\(x_ {2}, y_ {2}) :( 4, -5)

We found the slope:

m = \frac {y_ {2} -y_ {1}} {x_ {2} -x_ {1}} = \frac {-5 - (- 1)} {4-5} = \frac {-5+ 1} {- 1} = \frac {-4} {- 1} = 4

Thus, the equation is of the form:

y = 4x + b

We substitute one of the points and find b:

(x,y):(5,-1)\\-1=4(5)+b\\-1=20+b\\-1-20=b\\b=-21

Finally, the equation is:

y = 4x-21

Answer:

y = 4x-21

What is nearest whole number to 63.62
kvv77 [185]

Answer:

64

Step-by-step explanation:

Looking at the number 63.62, you see that 6 comes immediately after the decimal point.

Now if the number after the decimal point is more than 5 we round up by adding one to the number just before the decimal point which is 3 in this case.

Assuming the number after the decimal point was less than 5 we would round down adding nothing to the number just before the decimal point.
