Answer:
"a"→ 32
"b"→ 31
"c" → 34
"d" → 33
Step-by-step explanation:
In order to calculate the slope of a line, we can use this formula:
[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]
The procedure is:
- Choose two points on line.
- Substitute the coordinates into the formula and evaluate.
Then:
- Line "a" ( Points (0,2) and (-3,3) )→ [tex]m=\frac{2-3}{0-(-3)}=-\frac{1}{3}[/tex]
- Line "b" ( Points (0,-2) and (-1,0) )→ [tex]m=\frac{-2-0}{0-(-1)}=-2[/tex]
- Line "c" ( Points (0,0) and (3,3) )→ [tex]m=\frac{0-3}{0-3}=1[/tex]
- Line "d" → Since it is horizontal the slope is zero ([tex]m=0[/tex])
