```#include <stdio.h>
#include <math.h>
int main()
{
float xx[5],yy[5],nr=0,dr=0;
float x[5]={60,61,62,63,65},y[5]={3.1,3.6,3.8,4.0,4.1};
double sum_y=0,sum_xy=0,sum_x=0,sum_xx=0,sum_x2=0,slope=0,intercept=0,reg;
int i,n=5;
for(i=0;i<n;i++)
{
xx[i]=x[i]*x[i];
yy[i]=y[i]*y[i];
}
for(i=0;i<n;i++)
{
sum_x+=x[i];
sum_y+=y[i];
sum_xx+= xx[i];
sum_xy+= x[i]*y[i];
}
nr=(n*sum_xy)-(sum_x*sum_y);
sum_x2=sum_x*sum_x;
dr=(n*sum_xx)-sum_x2;
slope=nr/dr;
double fac = pow(10, 2);
slope=round(slope*fac)/fac;
intercept=(sum_y- slope*sum_x)/n;
reg= intercept + (slope*64);
printf("Slope: %.2f\nIntercept: %.3f\nRegression: %.3f",slope,intercept,reg);
return 0;
}
