Find the equation of a line perpendicular to y=x-3 that contains the point (2,1)
murzikaleks [220]

Answer:

y = -x + 3

Step-by-step explanation:

y = x - 3   This equation has a slope of 1

A line that would be perpendicular to the above line would then need a slope of -1

If the line has a slope of -1 and passes through (2, 1) then we can plug into

y = mx + b to get the 'b' value

1 = (-1)(2) + b

1 = -2 + b

3 = b

Equation would be y = -x + 3

the function f(x) = –x2 − 2x 15 is shown on the graph. what are the domain and range of the function? the domain is all real num
VMariaS [17]
-x^2 - 2x + 15 in vertex form is -(x^2 + 2x - 15) = -(x^2 + 2x + 1 - 16) = -(x + 1)^2 + 16

Therefore, domain is all real numbers and range is {y|y ≤ 16}.
