Given two points (x₁,y₁) and (x₂,y₂) the slope of the line that passes through theses points will be:m=(y₂-y₁)/(x₂-x₁)
We have two points A(-2,-2) and B(2,-2); therefore the slope will be:m=(-2+2)/(2+2)=0/4=0
slope-intercept form:y=mx +bm=slopeb=y-intercept =-2
y=0x-2y=-2
Answer: The slope of diagonal AB is 0 and its equation is y=-2

What is the slope of P=(4.5,-1) Q=(5.3,2).
Ulleksa [173]
\bf \begin{array}{lllll}
&x_1&y_1&x_2&y_2\\
%   (a,b)
P&({{ 4.5}}\quad ,&{{ -1}})\quad 
%   (c,d)
Q&({{ 5.3}}\quad ,&{{ 2}})
\end{array}
\\\\\\
% slope  = m
slope = {{ m}}= \cfrac{rise}{run} \implies 
\cfrac{{{ y_2}}-{{ y_1}}}{{{ x_2}}-{{ x_1}}}\implies \cfrac{2-(-1)}{5.3-4.5}\implies \cfrac{2+1}{5.3-4.5}
\\\\\\
\cfrac{3}{0.8}\implies \cfrac{\frac{3}{1}}{\frac{08}{10}}\implies \cfrac{\frac{3}{1}}{\frac{4}{5}}\implies \cfrac{3}{1}\cdot \cfrac{5}{4}\implies \cfrac{15}{4}\implies 3\frac{3}{4}

romanna [79]

Answer:

In first equation if we put the value of x and y (x=2,y=2)than,

3x+y=8

3×x+y=8

3×2+2=8

6+2=8

8=8

in second equation the value of x=2,y=1

x2+xy=6

x2+x×y=6

4+2×1=6

4+2=6

6=6

Answer:

C) (x+1, y-1)

Step-by-step explanation:

Because if you look at the corresponding points 1 is added to the x-value of the original point and 1 is subtracted from the y-value of the original point
