Answer:
Step-by-step explanation:
Answer: A
Step-by-step explanation:
We can solve this quadratic equation using factorisation method as follows
:x2−5x−36=0
x2+4x−9x−36=0
x(x+4)−9(x+4)=0
(x+4)×(x−9)=0
x+4=0orx−9=0
x=−4orx=9
Answer:
y = 2
Step-by-step explanation: Given in the question,
a co-ordinate = (-2,2)
x = -2
y = 2
Equation of the straight line
y = mx + c
here m = gradient of the line
c = y - intercept
we know that gradient of the horizontal line = 0
plug value in the equation above
y = (0)x + 2
y = 2
