Point Slope Form and Slope Intercept

Find the point slope form given a line with a slope of 4 going through the point (3,8)

• 8-y=4(3-x)

• y-8=4(x-3)

• y+8=4(x+3)

• y-3=4(x-8)

What is slope Intercept form

• m=yx+b

• y-y=m(x-x)

• y=mx+b

• y=bx+m

What is point slope form

• x-x₁=m(y-y₁)

• y=mx+b

• y-y₁=m(x-x₁)

• y₁-y=m(x₁-x)

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

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

• -1

• 1

• -3

• 5

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

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

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

• -1

• 1
