(a) The line passes through the points (0,7) and (3,0)
(b) The line given by the equation 3x-5y=15
(c) The line given by the equation y-4=3(x-9)
(d) The line that passes through the points (-2,-5) and (2,5)
(e) The line passing through the point (2,3) that is parallel to the line x+2y=-11
------------------------------------------------------
(a)
The y-intercept is obviously given, y=mx+b, b=7.
(b) and (c)
If you can start from Ax+By=C and solve for y in terms of x, then you can adjust into slope-intercept form and identify the y intercept.
which is slope intercept form.
.
(e)
You are looking for the equation and if you understood (b) and (c) exercise items, then you can figure how what to do to finish.
