What is the equation in point slope form of the line that passes through the point (−1, −3) and has a slope of 4?

y+1=4(x+3)

y−1=4(x−3)

y+3=4(x+1)

y−3=4(x−1)

y + 3 = 4(x + 1)

Step-by-step explanation:

The equation of a line in point- slope form is

y - b = m(x - a)

where m is the slope and (a, b) a point on the line

Here m = 4 and (a, b) = (- 1, - 3), thus

y - (- 3) = 4(x - (- 1)), that is

y + 3 = 4(x + 1)

f(2x−x2)=−3x2+6x−1

step-by-step explanation:

set up the composite function and evaluate.

f(2x−x2)=−3x2+6x−1
