Step-by-step explanation:
To find out which option is correct, we can write the equation in point-slope form ourselves.
Use the point-slope formula to write the equation in point-slope form. Substitute the
,
, and
for real values.
Since represents the slope, substitute
in its place. Since
and
represent the x and y values of a point the line intersects, substitute the x and y values of (5,1) into the formula as well. Substitute 5 for
and 1 for
. This gives the following equation:
Answer:
–7x + 20
Step-by-step explanation:
(2x2 – 3x)(3x2 + 2x – 1)
(4 – 3x)(2x + 5)
(4*2x) + (4*5) + (–3x*2x) + (–3x*5)
8x + 20 –15x
–7x + 20
