Which coordinate pair fits the set of coordinates {(0, 4), (-2, 1), (-4, -2)} defined by a linear function? A) (5, 12) B) (6, -4

spin [16.1K]

Answer:

Step-by-step explanation:

A linear function has an expression $f(x)=ax+b.$ If the set of coordinates {(0, 4), (-2, 1), (-4, -2)} defines a linear function, then

$\begin{array}{l}4=a\cdot 0+b\\1=a\cdot (-2)+b\\-2=a\cdot (-4)+b\end{array}.$

From the first equation, $b=4.$ Substitute it into the second equation:

$1=-2a+4,\\ \\-2a=-3,\\ \\a=1.5.$

Check it with the third equation:

$1.5\cdot (-4)+4=-6+4=-2.$

Hence the linear function is $f(x)=1.5x+4.$

Now check all options:

$1.5\cdot 5+4=7.5+4=11.5\neq 12.$

$1.5\cdot 6+4=9+4=13\neq -4.$

$1.5\cdot (-3)+4=-4.5+4=-0.5\neq -1.$

$1.5\cdot (-6)+4=-9+4=-5.$

Find the values of x and y for which the lines are parallel.

UkoKoshka [18]

The apex If the triangle is 40, bc it's alternate interior with 40, due to the parallel lines.
Now all angles sum 180 in a triangle:
y+10 + 77 + 40 = 180
y + 127 = 180
y +137 -127 = 180-127
y = 53
Now the y+10 + 40 + x-1 sum to 180 2nd they all make a straight line:
x-1 + 40 + 53+10 = 180
x + 102 = 180
x + 102 -102 = 180-102
x = 78
Therefore the correct answer is:
B.) x = 78, y = 53
