y=-2x-3

Step-by-step explanation:

Calculate the slope first. in this case its -2. Now write it next to the x in the equation, y=mx+c where m is the slope/gradient and c is the y intercept. To find the y intercept we have to look at where the line meets the y axis. Here we can see that the line meets the y axis at the point (0,-3). -3 is your y-intercept.

step-by-step explanation:

the multiplicative inverse of a fraction a/b is b/a. for the multiplicative inverse of a real number, divide 1 by the number. for example, the reciprocal of 5 is one fifth 1/5 or 0.2, and the reciprocal of 0.25 is 1 divided by 0.25, or 4.

answer: if you weigh 60 pounds on earth, on the moon you will weigh about 10 pounds. if you weigh 120 pounds on earth, you will weigh about 20 pounds on the moon. since weight is caused by the mass of two objects that are near each other, the bigger the objects, the more the force of gravity.
