Complete the equation of the line whose y intercept is (0,5) and the slope is -9
what does y equal?

In this question, we're trying to make an equation with the given information.

We know that:

With the information above, we can make the equation.

The equation would be represented as y = mx + b

m = slope

b = beginning point (or y-intercept)

Lets make the equation.

We know that the slope is -9, so we would plug -9 in m.

Your equation would currently look like this:

y = -9x + b

We know that the y-intercept is at (0,5), this means that the beginning point would be 5. You would plug in 5 to b.

Your equation should look like this:

y = -9x + 5

This means that y = -9x + 5

answer: the answer is 35%

step-by-step explanation:

similar triangles are triangles which have the same shape but not the same size. this means their angle measures are equal but their side lengths are not instead they are proportional. to solve, we will set up a proportion and solve.

a proportion is two equal ratios set equal to each other. we form the ratios by finding corresponding sides (sides which match to each other on both triangles by their position). out ratios will be one side of the small triangle over the corresponding side on the big triangle as shown below:

.

to solve the proportion, we'll cross multiply by multiplying numerator with denominator across the equal sign.
