I believe the scale factor is 3:4
If you compare corresponding sides, 45:60=3:4 and 30:40=3:4
2. a) absolute values for the slopes
y = mx + c
3/4, 9,-11, -1 = 3/4, 9,11, 1
the higher the slope, the steeper the graph. 11 is high,
y = -11x - 5
b) 1/4,3,-3/4,-8 = 1/4,3,3/4,8
smaller value is 3/4
the least steep graph will be in,
y = -3/4x + 7
c) 6,2,1, 1/2
1/2 is the smallest value.
y = 1/2x + 6
d) It would be less steep.
e) It would be shifted down.
f) y = -8x - 3
g) y = 1/4x + 9
h) y = 3x - 1
i) y = -5x - 10
Im bad at this but is it 11xy ? chile anyways
Substitute the variable terms with the coordinates and the equation is
3=1/3(5)+b
solve for b
