Could you show the problem? I am also bad at math but showing the whole problem might give you the right answer
Answer:
i think its 3 srry if im wrong
Step-by-step explanation:
C, i think you forgot an x
(x+11)+(x-7)
x+11+x-7
x+x+4
2x+4
To find the slope of a line, we need to know the slope formula. The slope formula is:
m = , with m being the slope and (x₁, y₁) being the coordinates of 1 point and (x, y) being the coordinates of the other. Now we can substitute the values of the points in our equation ( (1,4) and (4, -2) ) into the slope formula. Substituting, we get:
=
= =
=-2
That means that the slope of our line is -2.
4200 x 10 = 42000 + 21000 = 63000. i'm basing this off average 70 beats per second!!
