Question

A line intersects the points (3,-4) and

(1, 2). What is the slope-intercept
equation for this line?
y = -3x + [?]

Answer 1

the y intercept is 5. You take one of the points and plug the cooridnates into the equation. I used (1,2)
2=-3(1)+?
2=-3+?, move the 3 to the other side by adding 3 to bothe sides,
?=5
