<u>Let's solve this problem step-by-step</u>:
<u>First, let's set up the point-slope form</u>:
⇒ 
- (x₁,y₁) ==> point on the line
- m ==> value of slope of the line
<u>Let's examine what we are given:</u>
- (-2,9) ==> point on the line
- -8 ==> slope of the line
<u>Let's plug in all the known values in the point-slope form</u>:

<u>To convert from point-slope form to slope-intercept form</u>:
⇒ must solve for 'y'
⇒ (<em>in other words</em>) must isolate y to one side and everything else to
the other side
<u>Let's solve</u>:

<u>Answer: y= -8x - 7</u>

- tan(50) → <u>Choice A</u>
Step-by-step explanation:
tan(-α) = - tan(α)
tan(-50) = <u>- tan(50)</u>
Further more :
tan (-50) = - tan (50) ≈ 0,27
0.2 if you mean 2/10 or 2.5 if you mean 10/2
Answer: x-int: (-1/2,0)
y-int: (0,-1/4)
Step-by-step explanation:
x-5y+3=3x-y+4
x-int: x-5(0)+3=3x-0+4
x+3=3x+4
-2x=1
x=-1/2 ==>(-1/2,0)
y-int: 0-5y+3=3(0)-y+4
-5y+3=-y+4
-1=4y
y=-1/4 ==>(0,-1/4)
