Write an equation in point-slope form for the line through the given point with the given slope. (8, -3); m= -1/4

y - 3 = -1/4 (x - 8)

Step-by-step explanation:

When writing point-slope it should be arranged as showed("<" Is an arrow btw):

y - y = m (x - x)

y - y(< y-coordinate of known point)= m(< slope) (x - x(< x-coordinate of known point))

the answer is 31.27mph

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
