Answer:
Slope = -2
Y intercept = 4
Equation. y = -2x +5
Step-by-step explanation:
Using points, (1,2) and (3,-2)
Slope = (-2-2)/(3-1) = -4/2 = -2
Y intercept = 4
-2 = (y-3)/(x-1)
-2(x-1) = y-3
-2x +2 = y-3
y = -2x +2 +3
y = -2x +5
Answer:
1/2? i think thats correct
hope this helped

Answer:
The value of x is 35
Step-by-step explanation:
In order to calculate the value of x in the following parallelogram: 2x - 10
2x + 50, we would have to calculate the following formula:
m<QPS+m<PQR=180°
According to the given data we have the following:
m<QPS=2x - 10
m<PQR=2x + 50
Therefore, 2x - 10+2x + 50=180
4x+40=180
x=140/4
x=35
We are given the data here that there are 21 teams and that in the tournament, for each opponent, one team has to play with each other twice. The formula to follow here is T = n*(n-1)*z/2 where T is the total number of games played in total in the tournament, n is the number of teams who participated and z is the number of times they have to face in the eliminations. 2 is attributed to prevent the repetition of the count in the reverse of roles of the opponents. In this case, upon substitution, then T =21*20*2/2 = 420 games in total.
Answer:
A(...; 7)
x =-1/5
B(8; ...)
y = 48
The slope is 5
Step-by-step explanation:
y−5x=8
A(...; 7)
We know that y=7, we need to find x
7 - 5x = 8
Subtract 7 from each side
7-7 -5x = 8-7
-5x =1
Divide by -5
-5x/-5 = 1/-5
x =-1/5
B(8; ...)
We know x = 8 we need to find y
y−5x=8
y - 5(8) = 8
y - 40 =8
Add 40 to each side
y-40+40 = 8+40
y = 48
Now we need to find the slope
y - 5x =8
Add 5x to each side
y -5x+5x = 5x+8
y = 5x+8
This is in the form y = mx+b where m is the slope
The slope is 5
