Answer:

The answer is 9

Step-by-step explanation:

The formula for area of a triangle is 1/2bh. That means that the answer is the base multiplied by the height divided by 2. You can multiply 54 by 2. It gives you 108. If you divide 108 by 12, it gives you 9 (the base). If you plug in all of those numbers, it will give you something like this:

height= 12 area=54     54*2= 108          108/12=9                

1/2* 9* 12 = 54

That is extra proof, but the base of the triangle is 9.

Y
Inga [223]

Answer:

1/2

Step-by-step explanation:

y = mx + b is slope intercept form.

b = y intercept. where the line first passes through on the y axis

that number is 3.

y = mx + 3.

to find M (slope) you have to do RISE / RUN.

Run is going left or right from a point

Rise is going up or down from a point.

To make sure you find the slope, when you Rise and Run, it has to hit another point on the graph.

From the y - intercept 3, RISE (go up) 1 and RUN (go left) 2.

So, the slope is 1/2.
