Answer:
Step-by-step explanation:
Question 17
y-y1 = m (x-x1 )
so basically you plug in the (x,y) to y1 and x1 place
Remeber always times it by -1
so answer would be
y-2 = -1/3 (x+4)
Question 18
Pretend its 3x+2y =8
you need to find x or y first im going to find y first
so
- 2y = -3x +8
divide by 2 to isolate y
y = -3/2x - 4
plug it back into the equation
3x + 2(-3/2x) - 4
the x will cancel
so y= -4
Then
plug in the -4 in place of y
SO the Answer is YES because y is horizontal there is -4 = there will be (-3, -4)!
