Write the equation in point-slope form of the line that passes through the given point and has the given slope.
(4, -7); m = -1/4

• y + 7 = -1/4(x - 4)
• y - 4 = -1/4(x + 7)
• y + 7 = 4(x - 4)
• y - 7 = -1/4(x - 4)

Which of these represents standard form of a linear equation?

• y - y₁ = m(x - x₁)

• Ax + By = C

• y = mx + b

Given the coordinate points (2, 5) and (-3, -10) mark all equations that would represent the line, written in point slope form.

• y - 5 = 3(x - 2)

• y = 3x - 1

• $y\ =\ \frac{5-\ \left(-\ 10\right)}{2\ -\ \left(-3\right)}$

• y + 10 = 3(x + 3)

• y + 5 = 3(x+ 2)

Given the coordinate points (2, 5) and (-3, -10) mark all the equations that would represent the line, written in standard form.

• 3x - y = 1

• y = -3x +1

• -y + 3x = 1

• 1 = 3x - y

• y + 10 = 3 ( x + 3)
