Question

A line passing through the .1, 7 has a slope of -8 write an equation in point slope form for this line

Answer 1

y - 7 = -8(x - 1)

Explanation:

We are provided with some information

We are given point (1,7)

Slope = -8

Using a point slope form formula

y - y_1 = m (x - x_1)

m = -8

y_1 = 7

x_1 = 1

Inserting the given values into the equation

y - y_1 = m ( x - x_1)

y - 7 = -8 ( x - 1) ( point slope form)

Don't confuse slope intercept form with point slope form

Slope intercept form

y = mx + C

y - point y

m - slope

x - point x

C - intercept

Point slope form

y - y_1 = m(x - x_1)
