Question

Which is an equation in point slope form for the given point and slope? Point: (-3,7) Slope: 4

Answer 1

y-7=4x(x+3)

Explanation:

(The 4x is 4 times ...)

Answer 2

`y -7 = 4(x+3)`

Explanation:

Point-slope form is in the format of
`y-y_1 = m (x-x_1)`. When knowing a line's slope and a point it passes through, you can write an equation in that format. The
`m`,
`x_1`, and
`y_1` must be substituted for with real values.

The
`m` represents the slope, thus substitute 4 for
`m`.
`x_1` represents the x-value of one point the line passes through, while
`y_1` represents that same point's y-value. The line passes through (-3, 7), so substitute -3 for
`x_1` and 7 for
`y_1`. This gives the following answer and equation:

`y-(7) = 4(x-(-3))\\y -7 = 4(x+3)`
