Answer:
A. 
Step-by-step explanation:
Slope of PR = 
Where,
Slope of PR = 
Slope of RT =
Where,
Slope of RT = 
Therefore, the proportion that can be used to show that the slope of PR = the slope of RT is:
Answer:
B
Step-by-step explanation:
Find the equation of the line
slope=(y2-y1)/(x2-x1)
slope=(6-2)/(7-(-3))=4/10=2/5
slope is 2/5
y=mx+b
y=2/5x+b find b
input a point
6=2/5(7)+b
6=14/5+b
minus 14/5 from both sides
3 and 1/5=b
16/5=b
xintercept is when y=0
0=2/5x+16/5
minus 16/5 from both sides
-16/5=2/5x
times both sides by 5/2 to clear fraction
-8=x
xintercept is -8 or (-8,0)
Answer:
-.5=x or -1/2=x
Step-by-step explanation:
x+3=3x+4
-x -x
3=2x+4
-4 -4
-1=2x
/2 /2
-.5=x or -1/2=x
arc length, s=(radius, r)(angle in radians, q)
q=tan^-1(s/r)
SO that saying the answer is 1.4 radians and the equation is probs q=7/5=1.4
