Answer:y = 7xStep-by-step explanation:1: slope (m)- as the x-variable goes up by 1, the y-variable goes up by 7. So, the βy/βx = 7. Therefore, the slope is 7.2: y-intercept (b)- When x = 0, y also has to be 0, since all of the x-variables multiplied by 7 gives the related y-variable, without any adding.3: plug in- y = 7x + 0 --> y = 7x
