Solving Systems of Equations
#1y = 3x - 7 and y = -x + 1(2, -1)
#28x + 2y = -2 and y = -5x + 1(2, -9)
#34x + y = 8 and -3x - y = 0(8, -24)
#42x + 5y = 20 and 3x - 10y = 37(11, -0.4)
#53x + 2y = -10 and 2x - 5y = 7(-1.5, -2)

Final Question
Write an equation for the line that is parallel to y = 5x + 4 and passes through the point (0, 9).y = 5x + 9

Answer from: Quest

the direct variation says that:

$y \propto x$

then the equation is of the form is given by:

$y = kx$ where k is the constant variation.

from the given table:

consider any value of x and m(x)=y

x = 2 and m(x)=y = 3

substitute these value in [1]; we have;

$3 = 2k$

divide both sides by 2 we get;

$k =\frac{3}{2} = 1.5$

⇒ $m(x) = 1.5x$

check:

put x = -1 and m(x) = -1.5

substitute in the equation:

$m(x) = 1.5x$

$-1.5 = 1.5(-1)$

-1.5 = -1.5 true

therefore, the function m(x) represents a direct variation
