Question

find the point where a line with slope 1 and y-intercept (0, 4) intercepts a line through P(4, 8) and Q(-2, -1). What is the point of intersection

Answer 1

`the point where a line with slope 1 and y-intercept (0, 4)`
y=mx+b slope intercept form
where m is slope and b is y-intercept
now plugin m and b value

Answer 2

I get that, but why do I need to know points P and Q. Why are they even in the problem.

Answer 3

you have to find 2nd equation through those (p and q) points

Answer 4

y = mx + b
y = 1x + 4

Answer 5

then we can graph both equations to find out the intersection point
