A microscope shows an image of an object that is 40 times the object's actual size. So, the scale factor of the enlargement is 40. An insect has a body length of 4 millimeters. What is the body length of the insect under the microscope?

160 centimeters

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!
