Which of the following point-slope form equations could be produced with the points (1, 3) and (9, 7)? y + 3 = 2(x +1) y - 3 = 1/2(x - 1) y + 9 = 1/2(x + 7) y - 9 = 2(x - 7)

answer: c i think

step-by-step explanation:

the answer is b.)

< 1=< 2

i need more info. are you looked to see there mph? how much they deliver? how far they go?

step-by-step explanation:

the system of inequalities is

step-by-step explanation:

step 1

find the equation of the dashed line

we have the points

(0,0) and (3,1)

the line passes through the origin, so, is a direct variation

find the slope

the equation of the dashed line is

the solution of the inequality a s the shaded area above the dashed line

therefore

the equation of the inequality a is

step 2

find the equation of the solid line

we have the points

(4,0) and (0,4)

find the slope

the equation of the solid line is

the solution of the inequality b s the shaded area below the solid line

therefore

the equation of the inequality b is

step 3

the system of inequalities is
