Consider the formula for slope between two coordinate points, m, shown below.

m=y2-y1/x2-x1

which of the following equations is equivalent to the slope formula?

the answer is A

Step-by-step explanation:

if u see, to get Y2 on its own u have to first multiply x2-x1 on both sides

m(x2-x1)=y2-y1

and then to get Y2 alone u need to add Y1 to both sides

m(x2-x1)+y1=y2

where are the choices?

d) by the cross product property, ab^2 = bc multiplied by ad

step-by-step explanation:

we are given

in the given triangle abc

angle a is 90° and segment ad is perpendicular to segment bc

we can see that

triangle(abc) and triangle(abd) are similar because they have common side and same angle (90 degree)

so, triangles(abc) and abd are similar

since, they are similar

so, the ratio of their sides must be equal

we get

now, we can cross multiply

and we get

so, this could be step to prove it
