Answer 1

D?

Answer 2

since the line picture looks nice and crosses gridlines at whole numbers , you can simply look at the y-intercept value, and also the slope, 1 unit in the x direction, the thing moves down 3

Answer 3

yeah i got that

Answer 4

to get the answer real fast y=m*x + b

slope looks like -3 , y-axis intercept at -1


y = -3x - 1

Answer 5

thanks

Which equations in point-slope form are equations of the line that pass through the points (4, 5) and (−3, −1)?

Choose exactly two answers that are correct.

A. y - 3 = 7/6(x - 1)


B. y - 5 = 6/7( x - 4)


C. y + 1 = 6/7(x + 3)


D. y - 4 = 7/6(x - 5)
