Answer:
(-2, 1)
Step-by-step explanation:
consider the following equations: -x-y=1 y=x+3
For the lines to intersect, the values must be the same
-x-y=1
x + y = -1
y = -x - 1
Equating the y values
-x - 1 = x+ 3
-x-x = 3 + 1
-2x = 4
x = 4/-2
x = -2
Substitute x = -2 into y = x+3
y = -2 + 3
y = 1
Hence the required coordinate is (-2, 1)
Related angle is 45 degrees, set up a triangle and use exact trig values to solve for x and y, then rationalise the denominators
Yes the first one is the correct answer in this form of a graph
Answer:
No. It is an isoceles triangle. A scalene triangle would have NO equal angles.
