Step-by-step explanation:

Equation for circle centered at origin:

x² + y² = r².

Therefore r² = (-4)² + (-2)² = 20, r = √20.

Hence d = 2r = 2√20 = 8.94 (2d.p.)

Let s be an integer. Alonso claims that -s must always be less than 0. IIiana claims that -s is only sometimes less than 0. Whos
Elis [28]
Iliana is correct since an integer means a whole number that is not a fraction, which includes negative AND positive numbers. If s=4 than -s is negative (-4) But if we plug in a negative integer, like -5, the negative signs are eliminated and it becomes positive, therefore Alonso is wrong (-s=-(-5)=5) If the question was about a natural number Alonso would have been right since natural numbers are only from 0 and above

Which linear function has the same y-intercept as the one that is represented by the graph? On a coordinate plane, a line goes t
Zolol [24]

The line which is having same y intercept as the line which passes through points (-4,0) and (0,3) is y=2x+3.

Given Points through which the line passes through are (-4,0) and (0,3)

We have to find the equation whose y intercept is equal to the y intercept of the line whose points given above.

First of all we have to find the y intercept of the line which passes through (-4,0) and (0,3). Equation of line is :

y-y1=(y2-y1)/(x2-x1)*(x-x1)

y-0=(3-0)/(0+4)  *(x+4)

y=3/4(x+4)

y -intercept exists where x=0

put x=0

y=3

So the options are:

  • y=2x-4
  • y=2x-3
  • y=2x+3
  • y=2x+4

By putting the value of x in all options we will find

y=-4

y=-3

y=3

y=4

So the third option is correct.

Hence the line whose y-intercept matched with the given line is y=2x+3.
