Where do the lines y=2x+1 and y=-5x-6 intersect?

Answer:
(-1, -1)
Step-by-step explanation:
To find where two lines in slope-intercept form intersect, set them equal to each other.
2x + 1 = -5x - 6
7x = -7
x = -1
Knowing they intersect at x = -1, substitute -1 into either of the two equations to find the y-value of their intersection.
y = 2(-1) + 1
y = -2 + 1
y = -1
So the intersection point of the two lines is (-1, -1).
