Answer:

y-intercept is the constant -2
Slope is the coefficient of #x# which is 3

Explanation:

consider the standard form #y=mx+c# where m is the slope (gradient).

Comparing to #y=3x-2# we find by that the slope #m = 3#

The y-intercept is when the graph crosses the y-axis. The y axis is at #x=0# so we substitute #x=0# and we get:

#y=3(0)-2#

#y=-2#

So the y-intercept is the constant - 2
