Both have slope 4 and intercept 3 so they are coincident lines
Answer: y = (-2/5)x - 7
This is the same as writing 
======================================================
Explanation:
Any linear equation is of the form y = mx+b, known as slope-intercept form
m = slope
b = y intercept
We'll replace m with -2/5 and replace b with -7 to get y = (-2/5)x + (-7) which simplifies to y = (-2/5)x - 7
Answer:
RLS is a straight angle
RLT is an obtuse angle
TLS is an acute angle
TRL is not an angle
TLU is a straight angle
SLU is an obtuse angle
SLT is an acute angle
ULR is an acute angle
and ULS is an obtuse angle
Step-by-step explanation:
You really just have to look at the angles from either of the straight angles (angles that are 180°) perspective and see of they lean more to make a smaller angle by leaning towards the other end of the angle, or a large one by leaning away from the opposite end.
Answer:
x=−3 and y=7
Step-by-step explanation Solve: 7x+2y=−7for x:
7x+2y=−7
7x+2y+−2y=−7+−2y(Add -2y to both sides)
7x=−2y−7
