I don’t get it please help me out

Step-by-step explanation:

1

When the slope is positive, the graph goes from the lower left to the upper right.

Suppose the graph is y = 0.8x + 2. See the inserted graph to see what happens. See the first graph downloaded to see what the above sentence means. The graph is in red.

2

when b>0 the y intercept is above the x axis. The second graph is y = x + 5. It is in blue. The red graph is the same one as the one above.

Sorry, I'm only allowed 1 download. But the red line is for part 1 and the blue line is for part 2.

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
