The answer you are looking for is B. If you use the FOIL method (first,outer,inner,last) of multiplication, you will find that (x+5) times (x-5) is actually x^2+25. Hope this helps! Comment if you have questions!!! :)

“ write the equation of the line that goes through the point (6,3) and is parallel to y=-2/3x+5 “ ????

brilliants [131]

Answer:

see explanation

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

y = - $\frac{2}{3}$ x + 5 ← is in slope- intercept form

with slope m = - $\frac{2}{3}$

Parallel lines have equal slopes, thus

y = - $\frac{2}{3}$ x + c ← is the partial equation of the line

To find c substitute (6, 3) into the partial equation

3 = - 4 + c ⇒ c = 3 + 4 = 7

y = - $\frac{2}{3}$ x + 7 ← equation of line
