Y=x+4
3x+Y=-8
3x+x+4=-8
X=-3. Substitute the value of x
Y=-3+4
Y=1
(X,Y)= (-3,1)
So the answer is C
The space margin depends on light and weather conditions as well as terrain (road curvature, hills, trees or other obstacles).
The time margin depends on the space margin, your reaction time, and your speed of travel.
You may appear to have a lot of time or space in icy conditions, but that can be an illusion. A collision course on ice will result in a collision, regardless of the time or distance involved.
Insufficient information is provided to be more specific.
1)Parallel means they have to have the same slope. Since our equation is y=2/3x+1, a line parallel to that would be(using out points) -5=2/3(-4)+b.
To find the y-intercept, solve for "b".
b=-7/3
Our equation would then be y=2/3x-7/3
2)Perpendicular lines have opposite-reciprocal slopes. our previous equation was y=2/3x+1, so our new equation would be -5=-3/2(-4)+b. Now lets solve for b.
b=-11
So our perpendicular equation would be y=-3/2x-11
Hope that was helpful. :)
