Investigation of transmission of mass and heat in magnetohydrodynamics (MHD) flow over a plate inclined at an angle past semi-infinite porous plate is carried out in this study. MHD flow model is formulated by combining the electromagnetic laws with Navier-stokes equations. The equations that govern the flow are transformed into their dimensionless form. The numerical scheme in the form of Implicit finite centre difference is used to obtain a numerical solution to the equations in MATLAB. The numerical results are presented graphically by varying the parameters that emerged from the flow. Effects of porosity parameter, magnetic strength parameter, and the inclination angle are studied. Velocity profiles in all directions are reduced with increasing porosity, magnetic field and inclination angle while there is a raise in the temperature profiles with increasing porosity, magnetic field and surface inclination angle
