Answer:
2y = x - 7
Step-by-step explanation:
The general equation of the line is;
y = mx + b
where m is the slope and b is the y-intercept
To get the slope, we use the slope formula
m = (y2-y1)/(x2-x1)
(x1, y1) = (3,-2)
(x2,y2) = (1,-3)
m = (-3+2)/(1-3) = -1/-2 = 1/2
So we have the equation as;
y = x/2 + b
Multiply through by 2
2y = x + 2b
To get the y-intercept value, we substitute any of the points
Let us use the first point
While 3 will go for x , -2 will go for y; thus we have;
2(-2) = 3 + 2b
-4 = 3 + 2b
2b = -4-3
2b = -7
b = -7/2
So the equation is;
2y = x -7
Answer:
Step-by-step explanation:
we know that
The area of the right triangle ABC is equal to
the formula to calculate the distance between two points is equal to
we have
A(10, 7), B(5, 9), and C(3, 4)
step 1
Find the distance AB
A(10, 7), B(5, 9)
substitute in the formula
step 2
Find the distance BC
B(5, 9),C(3, 4)
substitute in the formula
step 3
Find the area
substitute the values
(-3,5)(-2,3)
slope = (3 - 5) / (-2 - (-3) = -2 / 1 = -2
y = mx + b
slope(m) = -2
use either of ur points...(-2,3)....x = -2 and y = 3
now we sub and find b, the y int
3 = -2(-2) + b
3 = 4 + b
3 - 4 = b
-1 = b
so ur equation is : y = -2x - 1 <==
Answer:
There is a loss of 2 yards.
Step-by-step explanation:
To find the overall gain or loss, we add or subtract there values.
Initially, we have 0 yards.
Records 14, so 0 + 14 = 14, that is, for now a gain of 14
Then loses 7, so 14 - 7 = 7, for now a gain of 7.
Then, 7 - 9 = - 2, so in all, there is a loss of 2 yards.
