Answer:
Step-by-step explanation:
Put x = -2, x = -1, ... , x = 2 to the equation of the function y = -4x + 5 and calculate the values of y:
for x = -2
y = -4(-2) + 5 = 8 + 5 = 13
for x = -1
y = -4(-1) + 5 = 4 + 5 = 9
for x = 0
y = -4(0) + 5 = 0 + 5 = 5
for x = 1
y = -4(1) + 5 = -4 + 5 = 1
for x = 2
y = -4(2) + 5 = -8 + 5 = -3
The correct option is A, which is {(5/7, 12/7)}.
<h2>Given to us,</h2>equation 1, 5x + 2y = 7,
equation 2, y = x+1
To solve the question, as given in equation 2 the value of y which is equal to x+1, Substitute the value of y in equation 1,
Now, we have the value of x, substitute the value in equation 2, to get y,
Taking LCM,
Hence, the correct option is A, which is {(5/7, 12/7)}.
