Answer:
(2,3)
Step-by-step explanation:
The answer would be 21 because its the same length as the other side.
Answer:
-303
Step-by-step explanation:
.............
(-1,5)(2,4)
slope = (4 - 5) / (2 - (-1) = -1/3
y = mx + b
slope(m) = -1/3
use either of ur points (2,4)...x = 2 and y = 4
now sub and find b, the y int
4 = -1/3(2) + b
4 = -2/3 + b
4 + 2/3 = b
12/3 + 2/3 = b
14/3 = b
so ur equation is : y = -1/3x + 14/3....however, this is not ur answer because it is not in standard form.
y = -1/3x + 14/3
1/3x + y = 14/3....multiply both sides by 3
x + 3y = 14 <=== standard form
This is a nice twist to see if you can read the graph and interpret what it means.
f(1) is the y value of the graph when x = 1
So start at x = 1 and find the y value. Go straight up. The point you reach is (1,3)
so g(1) = 2*f(1) - 1
g(1) = 2*3 - 1
g(1) = 5
Answer
g(1) = 5
