Cheryl is curious How different amount of sunlight will impact the growth of her tomatoes. She expose someone for tomatoes to varying amounts of sunlight in hours per day and recorded the change in their circumference is in centimeters after a week

Abit confused about what you mean, but i think you might be referring to slope intercept form: y = mx + bin that case b, or the y intercept is already given.(0,-1)find the slope by using the formulay2 - y1/x2 - x1the final slope will be 4/2, equivalent to 2.now your equation should look like thisy = 4/2x -1sorry if this didn’t you out!
