Find an equation of the line that contains the point (2 ,5) and is perpendicular to the line y equals one half x plus 4. use zstandard followed by zsquare with a graphing calculator to verify the equation.

  y = -2(x -2) +5

Step-by-step explanation:

The slope of the given line is 1/2, so the slope of the perpendicular line will be the negative reciprocal of that: -1/(1/2) = -2.

In a version of point-slope form, the equation of the line through the given point can be written as ...

  y = m(x -h) +k . . . . . for slope m and point (h, k)

For our slope of -2 and point (2, 5), the equation is ...

  y = -2(x -2) +5

step-by-step explanation:

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.
