Y=-2x-3,y=-2x+2 how many solutions does it have and is it parallel lines
1 answer:
Answer:
- 0 solutions
- yes, the lines are parallel
Step-by-step explanation:
The coefficients of x in each equation are -2, so the lines have the same slope. The y-intercepts are different in the two equations so the lines are parallel.
__
Parallel lines do not intersect, so there is no solution for x and y that will satisfy both equations.

Answer: y=1/2x-1
Step-by-step explanation:
To find the equation of the line that passes through the points, we need to find out slope, m.
We plug our points into this formula to find slope.
Our slope is 1/2. To find our y-intercept, b, we would plug any point into the equation for slope-intercept form.
y=mx+b
y=1/2x+b
1=1/2(4)+b
1=2+b
b=-1
Now that we know b, our equation is y=1/2x-1.
