Question

what is the y-intercept of the line that passes through the points (3,7) and (-2,-3)?

Answer 1

it crosses the y intercept at 1

Answer 2

first find the slope
slope = (y2-y1)(x2-x1)

Answer 3

then use point slope form to get the equation of line from that equation you will get y-intercept
point slope form is
y-y1 = m(x-x1)

Answer 4

After you get the equation of the line

At y-intercept

x=0

You get y-intercept :)
