lukranit [14]

Answer:

See below

Step-by-step explanation:

If you factor a^2-a-30 you get \left(a^2+5a\right)+\left(-6a-30\right)

= a(a+5)-6(a+5)

= a(a+5)(a-6)

That's where the a comes in

What is the equation of the line that passes through the point (4,-4) and has a slope of -3?
zhuklara [117]

The equation of the line that passes through the point (4,-4) and has a slope of -3 is y = -3x + 8.

<h3>How to find the equation of a line?</h3>

The equation of a line can be represented in slope intercept form as follows:

y = mx + b

where

  • m = slope
  • b = y-intercept

Therefore, the equation of the line that passes through the point (4,-4) and has a slope of -3 can be found as follows;

m = -3

Hence,

y = -3x + b

using (4, -4) let's find the y-intercept.

-4 = -3(4) + b

-4  = - 12 + b

b = -4 + 12

b = 8

Therefore, the equation is y = -3x + 8
