The image of the triangle RST when rotated 90° counterclockwise around the origin is (-15,5), (-15,15) and (-5,10)
<h3>
How to rotate the triangle?</h3>
The coordinates of RST are given as:
R = (5,15)
S = (15,15)
T = (10,5)
The rule of 90° counterclockwise around the origin is:
(x,y) -> (-y,x)
So, we have:
R' = (-15,5)
S' = (-15,15)
T' = (-5,10)
Hence, the image of the triangle when rotated 90° counterclockwise around the origin is (-15,5), (-15,15) and (-5,10)

Answer:
1). -4
2). -12
Step-by-step explanation:
Because algebra
Y = mx + b is slope intercept form
x = -10
y = 8
m = 6
1. Solve for b
8 = (6)(-10) + b
b = 68
2. Plug m and b back into your slope intercept equation
y = 6x + 68
The answer to this question would be -26
