Answer:
option a)
y = m(0.5) + 1.8
Step-by-step explanation:
Equation
<h3>
y = mx + c</h3>
represent the equation of straight line
here m = gradient of straight line
c = y-intercept
First find the gradient of the graph
<h3>
m = y2 - y1 / x2 - x1</h3>
= 4 - 3 / 4 - 2
= 1 / 2
Put the values in the equation of straight line
y =mx + c
4 = 1/2(4) + c
c = 2
y = 1/2x + 2
which is approximately equal to y = 0.5x + 1.8
Answer:
3
Step-by-step explanation:
The decimal for 1/2 is 0.5
Answer:
No
Step-by-step explanation:
Pythagorean Theorem is "a^2+b^2=c^2"
Step 1) 1^2+6^2=37
37=c^2
Step 2) The square root of 37 is 6.08
That's not 9
So they don't form a Pythagorean triple
