Which equation has a slope of 1/2 and passes through the point (1.2)? O x-2y+3=0
*+2y+3=0
*2y+3=0
x-2y 3-0

The answer is

Step-by-step explanation:

Equation of a line is y = mx + c

where

m is the slope

c is the y intercept

To find the equation of a line given a point and slope we use the formula

y - y1 = m(x - x1)

where

m is the slope

( x1 , y1) is the point

From the question the point is ( 1 , 2) and the slope is 1/2

Substitute the values into the above formula and solve for the equation

That's

We have the final answer as

$20.01

step-by-step explanation:

the sale price is (1.00 - 0.77)($87), or 0.23($87), or $20.01.

the direct variation says that:

then the equation is of the form is given by:

            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;

divide both sides by 2 we get;

⇒

check:

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

substitute in the equation:

-1.5 = -1.5                   true

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