Answer:
y = 3x - 10
Step-by-step explanation:
It's not an option, but you already said in the instructions that the y-intercept is -10.
y = mx + b
M is the slope and b is the y-intercept.
Ok here it is:
4x-5y=40
2x+10y=20
I used the second equation and decided to get x
2x+10y=20
Subtract 10y from both sides.
2x=-10y+20
Divide both sides by 2
x=-5y+10
Put that in for x for first equation
4(-5y+10)-5y=40
Distribute the 4
-20y+40 -5y =40
Combine like terms
-25y+40=40
Subtract 40 from both sides
-25y=0
Divide by -25 on both sides
y=0
Substitute the y in for the 2nd equation
2x+10(0)=20
2x=20
Divide both sides by 2
x=10
So x=10 and y=0
Answer:
Neither parallel nor perpendicular
Step-by-step explanation:
To tell whether two lines are parallel or perpendicular, look at their slopes.
Parallel lines will have the same slope. This isn't the case since the first line has a slope of 1 and the second has a slope of -1.
Perpendicular line have slopes that are negative inverses of the other. This also isn't the case for these two lines. Although the slopes have opposite signs, the numbers aren't inverses.
The two lines are neither parallel nor perpendicular.
