Question

can someone please help me with these? i dont get them at all

Answer 1

@Michele_Laino

Answer 2

rise/run pick a point on the line that has a coordinate then either go up, down or left or right to find another point on the line.

Answer 3

oh yeah i know about the rise over run, i just have absolutely no idea what it is

Answer 4

the general formula of the slope of a line, is:
\[\huge m = \frac{{{y_2} - {y_1}}}{{{x_2} - {x_1}}}\]
where \((x_1,y_1)\), and \((x_2,y_2)\) are two points of such line

Answer 5

oh yeah! i know how to like subtract them and i know that formula. :) but i just have no idea how to find the slope. i accidentally wrote them as ordered pairs on my assignment

Answer 6

for example, I consider the third line. As we can see such line passes at points (red points in your picture):
\((-5,-1)\) and \((5,-2)\), so we can write:
\(x_1=-5,y_1=-1,x_2=5,y_2=-2\) so the corresponding slope, is:
\[m = \frac{{{y_2} - {y_1}}}{{{x_2} - {x_1}}} = \frac{{ - 2 - \left( { - 1} \right)}}{{5 - \left( { - 5} \right)}} = \frac{{ - 1}}{{10}}\]

Answer 7

now, please do the same with other lines, you have to write the coordinates of the red points first

Answer 8

omg that makes sense!! thank you! i just have no idea like how to tell what the red points are

Answer 9
