Your answer would be c y=4x+2. Based on the formula y= Mx+b, b being your y intercept, the line starts on 4. This equation is the only one that adds four to it therefore it is c. We can also prove with the slope. The slope is rise over run, ( m is the slope). Moving 4 up and 1 to the right, the line is created, making this equation true and the correct answer.
