Write an equation in slope-intercept form for the line that has the given slope and contains the point. m=3;(-1,-2)

P(1,2)  m = 3    Since you are given a point and a slope, use the point-slope form for the equation of a line: y - y1 = m(x - x1)

y - 2 = 3(x - 1)

y - 2 = 3x - 3

y = 3x - 1 hope this helps

Step-by-step explanation:

Answer

y=3x+1

put in point slope form y-yone=m(x-x one)

y+2=3(x+1)

y+2=3x+3

y=3x+1

f(2x−x2)=−3x2+6x−1

step-by-step explanation:

set up the composite function and evaluate.

f(2x−x2)=−3x2+6x−1

the first one is x^2+2x+2

the second one is x^2+4

the last one is x^2-4x+8
