Question 519003
Use the "slope-intercept" form to determine the slope remembering that parallel lines have identical slopes.
Slope-intercept form:
{{{y = mx+b}}} where m = the slope and b = the y-intercept.
1) {{{y = 0.5x+4}}} Here, m = 0.5 and b = 4.
2) {{{y = 6}}} Here m = 0 and b = 6.
3) {{{7x-y = 5}}} Rearrange this to:
{{{y = 7x-5}}} m = 7 and b = -5.
4) {{{y = 4x-8}}} Here m = 4 and b = -8
