For the equation
y - 3 = 2(x + 4),
which of the following is true?

• The line has m = 2 passing through the point (4, -3)

• The line has m = 2 passing through the point (3, -4)

• The line has m = 2 passing through the point (-4, 3)

• The line has m = 2 passing through the point (-3, 4)

Through: (-5,0), slope=4/5

Through: (2,-4), slope = 1/4

For the equation y = -3 (x - 5) - 1, the line contains the point (5, -1) and has a slope of?

• -1

• 1

• -3

• 5

write down the equation of the line if

gradient = 3/4
y-intercept = -1/2

Write the equation of the line in point-slope form and then slope intercept form using the given information
(1, 2) m=7

• y-1 = 7(x - 2)
  y=7x+1

• y - 2 = 7(x - 1)
  y=7x-5

• y - 2 = 7(x + 1)
  y=7x+5

• y - 7 = 2(x - 1)
  y=7x-13
