Step-by-step explanation: Since the y coordinate is intercepting the y axis, the y-intercept is 3. To find the slope, the formula is change of y over change of x. The coordinates on this plane is (0,3) and (-3,0). That means the equation is (3-0) divided by (0-(-3)). That equals 3 divided by 3 which is obviously 1. Mark Brainliest plz!
