What are (2,1) and (0,-3) in slope-intercept form pls. I will give you brainiest
kotykmax [81]

Answer:

Well, the first thing you must do is find the slope

(0,2) (1,-3) I am going to make x1= 0, y1=2, x2=1 and y2= -3

Now, I am going to use the formula for the slope, which is

y2-y1/(x2-x1)

[-3-2]/(1-0)= -5/1 or just -1

Next, I am going to use the point slope form, which is

y-y1=m(x-x1). m=5, x1=0, y1=2

y-2= -5(x-0)

y-2=-5x

+2 +2

y= -5x+2 This is the slope intercept form.

we are done. I am glad to see that you are doing math on a Saturday night.. Good luck... Please rate my answer:)

I) Coordinates of point P
SSSSS [86.1K]

Given:

Five points P, Q, R, S ,T on a coordinate plane.

To find:

The coordinates of (i) P, (ii) Q, (iii) T, (iv) (Ordinate of T) – (Abscissa of R) and (v) (Abscissa of Q) – (Ordinate of S).

Solution:

From the given graph it is clear that the coordinates of given points are

P = (1,1)

Q = (-3,0)

R = (-2,-3)

S = (2,1)

T = (4,-2)

(i)

Coordinates of point P are (1,1).

Therefore, the correct option is (a).

(ii)

Coordinates of point Q are (-3,0).

Therefore, the correct option is (b).

(iii)

Coordinates of point T are (4,-2).

Therefore, the correct option is (c).

(iv)

Ordinate is y-coordinate and abscissa is x-coordinate.

Ordinate of T = -2

Abscissa of R = -2

(Ordinate of T) – (Abscissa of R) = -2 - (-2)

                                                     = -2 + 2

                                                     = 0

Therefore, the correct option is (c).

(v)

Abscissa of Q = -3

Ordinate of S = 1

(Abscissa of Q) – (Ordinate of S) = -3 - 1

                                                      = -4

Therefore, the correct option is (a).
