HELP PLEASE, ITS DUE TODAY IN AN HOUR!!
Schach [20]

Answer:

D

Step-by-step explanation:

the equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

If m > 0 , then line slopes upwards from left to right

If m < 0 , then line slopes downwards from left to right

y = 3x - 2

has m > 0 and c = - 2 , thus line slopes upwards crossing the y- axis at - 2

y = - 2x + 3

has m < 0 and c = 3, thus line slopes downwards crossing the y- axis at 3

on the graph this is the lower blue line and the red line

the solution to the system is at the point of intersection of the 2 lines

This is at point D
