Answer:
y = 2x + 2 
Step-by-step explanation:
The general form
is;
y = mx + b
where m is the slope and b is the y-intercept 
so we have;
y = mx + 2
To get m, substitute the point (-1,0)
So we have 
0 = -m + 2
m = 2
So the equation is;
y = 2x + 2 
 
        
             
        
        
        
Answer:
12 units
Step-by-step explanation:
Given that :
R(-3,2) 
S(2,2) 
T(2,-5). 
The total length ;
Distance between two points : √[(x2 - x1)² + (y2 - y1)²] 
Distance between R and S :
R = (-3,2) 
S(2,2) 
√[((2 - (-3))^2 + (2 - 2)^2] 
Sqrt(5^2 + 0^2) 
D1 = 5 units 
Distance between S and T:
S(2,2) 
T(2,-5). 
D2 = √[(2 - 2)^2 + (-5 - 2)^2]
D2 = sqrt(0^2 + (-7)^2)
D2 = 7 units 
Hence, total length = D1 + D2 = (5 + 7) = 12 units
