you had nothing for 1. and I am not sure what you mean by 4.
This is a list of all answers
Answer:
Y=-1/2x+4
Step-by-step explanation:
-The slope is -1/2 so you just plug it in where the slope would go with an x in front
-all you need now is your y-intercept which can be found by plugging in the provided info to your basic form y=mx+b
-You can take the provided point at (10,-1) and work out what the intercepts is
-1=-1/2(10)-b
-1=-5-b
4=b
Answer:
∠ XYZ ≈ 72.9°
Step-by-step explanation:
Using the tangent ratio in the right triangle
tanXYZ =
=
=
, thus
XYZ =
(
) ≈ 72.9° to 1 dec. place )
Answer:
≈ 7.07
Step-by-step explanation:
Calculate the length using the distance formula
d = √ (x₂ - x₁ )² + (y₂ - y₁ )²
with (x₁, y₁ ) = (0, - 1) and (x₂, y₂ ) = (- 7, - 2)
d = 
= 
=
=
≈ 7.07
Ill give u the answer hold up i gotta do the work
