\bf \begin{array}{lllll} &x_1&y_1&x_2&y_2\\ % (a,b) &({{ 0}}\quad ,&{{ d}})\quad % (c,d) &({{ d}}\quad ,&{{ 0}}) \end{array} \\\\\\ % slope = m slope = {{ m}}= \cfrac{rise}{run} \implies \cfrac{{{ y_2}}-{{ y_1}}}{{{ x_2}}-{{ x_1}}}\implies \cfrac{0-d}{d-0}\implies \cfrac{-d}{d}\implies -1

Answer:

-1

Explanation:

Hello,

The slope is the inclination of the line with respect to the abscissa axis, if you know two points it can be calculated using:


P1(x_(1),y_(1) )\\P2(x_(2),y_(2) )\\\\slope(m)=(y_(2) -y_(1) )/(x_(2)-x_(1)) \\

Step 1

Define


P1=a(o,d),x_(1) =o, y_(1)=d \\P2=b(d,o),x_(2) =d, y_(2)=o

Step 2

put the values into the equation


slope(m)=(y_(2) -y_(1) )/(x_(2)-x_(1))\\slope(m)=(o-d)/(d-o)\\factorize -1\\\\slope(m)=-(-o+d)/(d-o)\\slope(m)=-(d-o)/(d-o)\\slope(m)=-1\\

Have a great day
