Answer:

y = x - 2

Step-by-step explanation:

1. Find the slope - change in y/change in x

$\frac{0-(-1)}{2-1}$ = 1

Slope is 1

2. Find y-intercept

y = x + b

Substitute a point (2,0)

0 = 2 + b

b = -2

3. Put the equation together

y = x - 2

9 Given: p + q = 25. r + s = 25. q = r. Prove: p=s

MrRissso [65]

This is about simultaneous equations.

p = s has been proved below.

We are given;

p + q = 25 - - - (eq 1)

r + s = 25 - - - (eq 2)

q = r - - - (eq 3)

Let's put r for q in eq 1 to get;

p + r = 25 - - -(eq 4)

Let's subtract eq 2 from eq 4;

(p + r) - (r + s) = 25 - 25

p + r - r - s = 0

p - s = 0

p = s

I need help figuring out the coordinate planes of these points ASAP.

d1i1m1o1n [39]

Given:

The vertices of the quadrilateral WXYZ are W(2,4), X(4,2), Y(2,1) and Z(0,2)

The graph is rotated 90° about the origin.

We need to determine the coordinates of the quadrilateral W'X'Y'Z'

Coordinates of the quadrilateral W'X'Y'Z':

The rule to transform the coordinates 90° counter clockwise about the origin is given by

$(x, y) \implies(-y, x)$

Let us substitute the coordinates.

The coordinates of W' is given by

$W(2,4)\implies W'(-4,2)$

The coordinates of X' is given by

$X(4,2) \implies X'(-2,4)$

The coordinates of Y' is given by

$Y(2,1) \implies Y'(-1,2)$

The coordinates of Z' is given by

$Z(0,2) \implies Z'(-2,0)$

Therefore, the coordinates of the vertices W', X', Y' and Z' are (-4,2), (-2,4), (-1,2) and (-2,0) respectively.
