X = 10
Step-by-step explanation:
the triangles are similar meaning one is smaller we have all the sides on the smaller one
10 to 25 is a 2.5 increase
so 4 x 2.5 = 10
Answer:
slope = 2 because it goes up by 2 and across 1
10 = 2(1)+b
10=2+b
-2 -2
b = 8
y intercept = 8
equation: y = 2x+8
yes it is proportional because it has a constant rate of change or slope
