Would -x+2y=5 be on the graph of a straight line

Plotting this equation will result in a straight line.

This is because x and y are without exponents, and it doesn't matter in what for the equation is. It can be in standard for, slope-intercept form, or point slope form. This is in standard form.

To make this easier, you can plot this equation into a  graphing calculator, like desmos (online), and write down this equation in the bar just to see the result

sorry if this isnt what you're looking for i dont really understand the question

option a is correct.

step-by-step explanation:

scale factor: it is used to find proportional measurements.

proportions means having the same ratio.

scale factor is the ratio of the model measurement to the actual measurement in a simplest form.

or we can say that the ratio of any two corresponding lengths in two similar geometric figures

if the scale factor is more than 1, then it is an enlargement,

if the scale factor less than 1, then it is a reduction.

given the two geometric figure:

by definition of proportions, we have
