**
Standard form of equation for a straight line: y=mx+b, m=slope, b=y-intercept
Slope of given line=change of y/change of x=∆y/∆x=(2-(-1/2))/(3/4-1/4)=(5/2/1/2)=10/2=5
equation: y=5x+b
solve for b using (x,y) coordinates of one of given points (3/4,2)
2=5*3/4+b
8=15+4b
4b=-7
b=-7/4
Equation of given line:
y= 5x-7/4
