Question 1022191: At what point does the line with the equation y=2x+3 intersect with the line with the equation y=-1/2x-7 Answer by macston(5194) (Show Source):
You can put this solution on YOUR website! .
y=2x+3 (RED LINE on graph)
(-1/2)x-7=y (GREEN LINE on graph)
.
Intersection when:
.
2x+3=(-1/2)x-7:
2.5x=-10
x=-4
.
y=2x+3
y=2(-4)+3
y=-8+3
y=-5
Intersection at (-4,-5)
.
CHECK:
y=(-1/2)x-7
y=(-1/2)(-4)-7
y=2-7
y=-5
.
