Writing Linear Equations Given Two Points Answers

The first step of writing an equation when given two points is the same for both strategies, slope-intercept or point-slope forms. What would be the first step in finding the equation of the line that passes through (5, 1) and (3, 5)?

b =

y = (1/2)x – 8✔ y = -2x + 2y = 2x – 14y = -2x – 8

The equation of line B is .

m =

y = one-third x + 3

y = x + 67 = –1(–1) + by – 4 = –1 (x – 2)y – 7 = –1 (x – (–1))y – 2 = x – 4y = –x + 6

In which step did Helena make an error?

Use point-slope form, y - y1 = m(x - x1), to find the linear equation of a line that passes through the points (2, -1) and (10, 7).

Use point-slope form, y - y1 = m(x - x1), to find the linear equation of a line that passes through the points (2, -1) and (10, 7). y = x +
