Answer:

The line meeting the criteria is y = (1/2)x + 6 does not match any of the answer options.

Explanation:

Let's use the slope-intercept form of a linear equation: y = mx + b, where m is the slope and b the y-intercept (the value of y when x = 0). We are given the slope, (1/2), so let's put that into the equation:

y = (1/2)x + b

It is the value we choose for b that will make the line pass through point (6,-3). We can determine that value by entering the given point in the equation and then solving for b:

y = (1/2)x + b

-3 = (1/2)*(6) + b for point (6,-3)

-3 = 3 + b

b = -6

The full equation is thus y = (1/2)x + 6

See the attached graph.

The `list of options doesn't have an equation that matches this conclusion. The first two aren't even equations. Assuming for the moment they are mistyped and should have an "=" sign after the y, we will change the list as follows:

Original New

y-2x+6 y=2x+6

y-1x-6 y=1x-6

y=2x-3 y=2x-3

y=x+3 y=x+3

The slopes are either +1 or +2. None have the required slope of (1/2)
