I assume this is the intersection of two lines, i.e. -1/2y is (-1/2)y. Please tell me if it's really -1/(2y).
(-1/2)y=(1/2)x+5
Multiplying both sides by -2
y = - x - 10
The other equation is
y = 2x + 2
We can equate them to find the meet
y = - x - 10 = 2x + 2
-3x = 12
x = -4
y = 2x + 2 = -6
Check: (-1/2)y=3, (1/2)x+5=3, equal, good
2x+2=2(-4)+2=-6=y, good
Answer: x=-4, y=-6
Answer:
A
Step-by-step explanation:
<h3>
<u>Explanation</u></h3>
- Find the slope by using rise over run with two given coordinate points.
- Substitute the coordinate values in.
We have got the value of slope. Substitute in the slope-intercept form.
Substitute and Rewrite the equation.
- Find the y-intercept or the value of b by substituting any given coordinate points.
I will substitute (2,8) in.
Rewrite the equation by substituting the value of b.

F(-3) = 4(-3) + 5
F(-3) = -12 + 5
F(-3) = -7
