ANSWER
(1,-3)
EXPLANATION
The given equations are:
y = 5x - 8
y = 4x - 7
We equate the two equations to get:
5x - 8=4x - 7
Group similar terms:
5x - 4x=-7+8
Simplify bottom sides
x=1
Put x=-15 into the first equation:
y=5(1)-8
y=-3
(1,-3)
The solution is (1,-3)

Answer:
y = 2 - ( x - 1)²/9
Step-by-step explanation: See Annex
As the parameter t increases, the value of x increases and the value of y decreases, we get the figure of the annex ( the arrow in the Annex indicates the way of the curve with t increasing.
b) to eliminate the parameter:
x = 1 + 3*t (1) y = 2 - t² (2)
Then from equation (1) t = ( x - 1 ) / 3
plugging that value in equation (2)
y = 2 - [ ( x - 1 ) / 3 ]²
y = 2 - ( x² + 1 - 2*x)/9
9*y = 18 - x² + 1 - 2*x or y = 2 - ( x - 1)²/9
The curve is a parabol
