y = 2x + 3
Step-by-step explanation:
The gradient (2x) is the same since the lines are parallel
The y-intercept(+3) is different however, since this line passes through co-ordinate (-1,3) It is +3 because in a co-ordinate the x and y co-ordinate is in this order (x,y). Therefore, the y number represents which y co-ordinate the line passed through the y axis.
