For the graph x = -3 find the slope of a line that is parallel to it. A.-3
B. undefined
C.-1/3
D.0

D

Step-by-step explanation:

For parallel lines, they have the same slope, but different y-intercepts.

x=-3 has a slope of 0 because it is a vertical line. Therefore, the slope of the line that is parallel to is is also 0.

d) 30 units^2

area of rectangle = l × b

we know,

length = 10 unit

breadth = 3 unit

applying the formula,

= l × b

= 10 × 3

= 30 unit^2

2.2°  

step-by-step explanation:

let θ = the angle of elevation.

tanθ =77/2020

tanθ = 0.038 12

      θ = tan⁻¹0.038 12

      θ = 2.2°
