choose the equation below that represents the line passing through the point (2, −4) with a slope of one half. y = one halfx 5 y = one halfx − 3 y = one halfx − 5 y = one halfx 3
Hello,
One half may be written 0.5=1/2=12^(-1).
y+4=(x-2)1/2==>y=x/2-5
Answer C
Answer:
\(y=\frac{1}{2}x-5\)
Therefore, option 3 is correct.
Step-by-step explanation:
We have given a slope and one point we need to find the equation with given point and slope
Using the formula:
y = mx+b
Where m is the slope
And x,y is the given point On substituting the values we get:
Here, \(m=\frac{1}{2},x=2,y=-4\)
\(-4 =\frac{1}{2}(2)+b\)
\(1+b=-4\)
\(\Rightarrow b=-5\)
Now, plugging b in the equation y =mx+b we get the required equation so we get:
\(y=\frac{1}{2}x-5\)
Therefore, option 3 is correct.
