50*8=400
400+175=575
it subtracted 575 on the last round
Our parent function is f(x)=x^2. A vertical stretch by a factor of k means that every point (x,f(x)), has been transformed into (x,kf(x)). Alex is clearly incorrect as our parent function has been transformed to (x,9f(x)), not (x,3f(x)). A horizontal stretch(or compression) by a factor of k means our function has been transformed to (x/k,f(x)). Here, Marta is saying our function should look like (3x,f(x)). This can also be achieved by plugging 3x into the parent function, which would give us f(3x)=(3x)^2, so it seems that Marta is the correct one.
Answer:
<h2>a = 3</h2>
Step-by-step explanation:
The slope of a line given two points can be found by using the formula

From the question the slope is - 3
To find the value of a we have

Divide both sides by - 3

We have the final answer as
<h3>a = 3</h3>
