The two triangles are similar. <span>When two </span>figures<span> are </span>similar<span>, the ratios of the lengths of their corresponding sides are equal. We use this fact in order to calculate the height of the bigger triangle. We do as follows:

QP / SL = MN / SL+SR
25 / SL = 35 / SL + 13
SL = 32.5

Area = height x base / 2
Area = SL x MN / 2
Area = 32.5 x 35 / 2 = 568.75

To find the rate of change, or slope, pick two points. The slope, is change in y coordinates over change in x coordinates.
slope =  \frac{y2-y1}{x2-x1}.

In this case, the slope is 
\frac{-11+1}{2-0} =  \frac{-10}{2} = -5.
Remember that subtracting a negative number equals adding the number without the negative sign.
a-(-b) = a+b

Now for the y-intercept. The y-intercept is where the graph intersects the y-axis, where x = 0.
You have the coordinate (0, -1), where x = 0. So the y-intercept is -1.

Putting these values into the slope-intercept form y = mx+b, the equation is
y = -5x - 1

Answer:

Step 1: Multiply 1x5 Step 2: Multiply 2x3 Step 3: Add the two products

d=v*t

d=distance

v=velocity(speed)

t=time

distance is equal to the product of velocity and time, equation form;

d=vt
