Answer:
0.75
Step-by-step explanation:
Each 1/4 is a quarter so multiply 0.25*3 which equals 0.75
 
        
                    
             
        
        
        
Y = 3/2x + 4
Add the 8 to both sides and then divide all the terms by 2

Answer:    y = x+1</h3>
===================================================
Explanation:
f(x) = x^3 - 2x + 3
f ' (x) = 3x^2 - 2 ..... apply the power rule
f ' (1) = 3(1)^2 - 2 ... plug in x coordinate of given point
f ' (1) = 1
If x = 1 is plugged into the derivative function, then we get the output 1. This means the slope of the tangent line at (1,2) is m = 1. It's just a coincidence that the x input value is the same as the slope m value. 
Now apply point slope form to find the equation of the tangent line
y - y1 = m(x - x1)
y - 2 = 1(x - 1)
y - 2 = x - 1
y = x - 1 + 2
y = x + 1   is the equation of the tangent line.
The graph is shown below. I used GeoGebra to make the graph.
