Which of the points shown below are on the line given by the equation y = x - 1

  B, C, D

Step-by-step explanation:

Subtract 1 from the x-value and see if that's the value you have for y.

  A: 1 -1 = 0 . . . . not 2

  B: 2 - 1 = 1 . . . yes

  C: 4 - 1 = 3 . . . yes

  D: -3 -1 = -4 . . . yes

You can also draw a line on the graph with slope 1 and through y-intercept -1. It will pass through points D, B, and C. It will miss point A.

p ÷ r = tan(x)

step-by-step explanation:

given that there is a figure below shows a right triangle: a right triangle is shown with hypotenuse equal to q units and the length of the legs equal to p units and r units.

graph is missing so i will create the graph as per given information.

the angle between the legs having lengths p units and q units is y degrees. the angle between the legs having lengths r units and q units is x degrees.

now we need to find about what is p ÷ r equal to.

so we can use trigonometric ratio tan(x)=[altitude]/[base] to find the value of p ÷ r, because p is the altitude and r is the base.

p ÷ r=tan(x)

hence final answer is p ÷ r=tan(x).
