Answer:
5.6 = AC
Step-by-step explanation:
We know that the length of BD is congruent to the length of AC, therefore we can say:
<em>BD ≅ AC</em>
4.8 * 1.6 = 3.2 * x
7.68 ≅ 3.2x
7.68 / 3.2 ≅ x
2.4 = x
Therefore length of AC would be:
<em>3.2 + x = AC</em>
3.2 + 2.4 = AC
<u>5.6 = AC</u>
Hope this helps!
In the slope intercept formula (y = mx + b)
the m = slope
the b = y intercept
hope this helps :)
you have to rearrange the equation to match the formula
so.....
-y = 6x - 6
m = 6x/-y = -6 (you can just see it as 6/-1 you dont have to count the x and y)
b = -6
