I can’t see the graph — you need the y-coordinate of the point on the line where x = 1. Point-slope form is y − y1 = m(x − x1), so here the blank is y1, the y-value at x = 1.
For example:
- if the line goes through (1, 4) then the equation is y − 4 = −3(x − 1),
- if it goes through (1, −1) then y − (−1) = −3(x − 1), i.e. y + 1 = −3(x − 1).
Upload the graph or tell me the y-coordinate at x = 1 and I’ll fill in the blank.
