Help! I completely forgot how to do this

y=-0.5x-2

Step-by-step explanation: you have to put it into y=mx+b form.

First find the y-intercept,-2, where the y-axis crosses with the x-axis then use the equation y2-y1/x2-x1 to find the slope, you could use the points -5,6 and 0,-4 which gives you:  -0.5 so then if you put it into an equation you get y=-0.5x-2

total amount to be paid = $19.5

step-by-step explanation:

given ,

original price = $25.99

discount = 25%

discount amount = 25% of original price

discount amount = 25/100   * 25.99

discount amount = $6.49

hence , the total amount to be paid = original price - discount amount

                                                            = $25.99 - $6.49

                                                            =$19.5

total amount to be paid = $19.5

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
