What is the slope of the line shown in the graph? a coordinate plane graph is shown. points are plotted at 0 comma 3 and 1 comma 1. the points are joined by a line. −1 −2 negative 1 over 2 2

the equation is y = -2x + 3.

Step-by-step explanation:

As we move from (0, 3) to (1, 1), x increases by 1 and y decreases by 2.

Hence, the slope of the line connecting these two points is

m = rise / run = -2/1, or just m = -2.

Starting with y = mx + b, and using the point (0, 3) and the slope m = -2, we get an expression for the y-intercept, b:

3 = -2(0) + b.  Thus, b = 3, and the equation is y = -2x + 3.

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
