help fixing small error!

[mikey108]

I'm supposed to find the equation of a line and the slope but I keep getting an error on line 17 that says

error: expected ';' before '{'

. Don't know how to fix it. Please help, thanks!

#include <iostream>
using namespace std;

int main () {
double x1, y1, x2, y2, m, b;
cout << " Enter X1: " << endl;
cin >> x1;
cout << " Enter Y1: " << endl;
cin >> y1;
cout << " Enter X2: " << endl;
cin >> x2;
cout << " Enter Y2: " << endl;
cin >> y2;
if (x1 == x2) {
cout << " The slope is undefined." << endl;
}
else m = (y2-y1)/(x2-x1) {
cout << " The slope is: " << m << endl;
b = y1-(m*x1)
cout << " The y-intercept is: " << b << endl;
}

return 0;
}

[petersrolo]

else m = (y2-y1)/(x2-x1) {
cout << " The slope is: " << m << endl;
b = y1-(m*x1)
cout << " The y-intercept is: " << b << endl;
}

return 0;
}

should look like

else {
 m = (y2-y1)/(x2-x1);
cout << " The slope is: " << m << endl;
b = y1-(m*x1);
cout << " The y-intercept is: " << b << endl;
}

return 0;
}

There was a semi colon missing at the end of line 19 as well.

else if ( m = (y2-y1)/(x2-x1) )
{
        cout << " The slope is: " << m << endl;
        b = y1-(m*x1);
        cout << " The y-intercept is: " << b << endl;
}

Is this what you wanted?

missing semicolon
line 17 else m = (y2-y1)/(x2-x1);
line 19 b = y1-(m*x1);
