I. write the equation for the line that passes through (-5, -4) and (3, 12). Step 1. Label the ordered pairs. (X1, y1) and (X2, yz) Calculate the slope. m = 2 y1 ( ) - ( ) = X2- X1 ( ) -( ) Step 2. Now, you know m = Choose one of the ordered pairs (either one will work) ... ( x, _ need a SLOPE a POINT to write Insert the m, x, and y in the slope intercept equation, _y = (m )( x ) + b an equation! Solve for b
