The a value affects the graph by vertically stretching or compressing the graph.
The r and s values affect the zeros, or x intercepts of the parabola, and therefore the vertex.
Hope this helps!
10 - nw is less than or equal to 8
n = number
If we try to simplify the ratio or try to multiply both by any number, we will get the equivalent ratio
Like :

Divide ( simplify ) by 2

Or multiply by any number,

From the example, 2 / 3 and 8 / 12 are equivalent ratios to 4 / 6
The correct answer is B. For sure it is. It took a while to solve in my head
Sorry i’m not gonna graph it but with this info u easily can
the y intercept is -1
slope is 3/1
final equation is y=3x-1
