Answer:
:)
Step-by-step explanation:
well if you take 35x, which is 35 times whatever, + 70, you get y. so the first one is 35(1) + 70 = 105.
so i’ll go in order
35 x 1 + 70 = 105
35 x 2 + 70 = 140
35 x 3 + 70 = 175
35 x 4 + 70 = 210.
just multiply then add 70
hope this helped
1) find slope. when its perpendicular, It will be a negative reciprocal to the given slope so m1= -1/m1
m=-1
2)
y =-1x+b
(-3)=-1(2)+b
-3=-2+b
b=-1
3) y=-1x-1
hope I helped!
