Answer:
NOT the graph A and the graph B.
Step-by-step explanation:
y = mx + b
m - slope
b - y-integer
If m > 0 then the function is increasing.
if m < 0 then the function is decreasing.
We have y = -2x + 3
m = -2 < 0 the function is decreasing
b = 3 y-intercept = 3
The x-intercept: y = 0. Substitute
0 = -2x + 3 add 2x to both sides
2x = 3 divide both sides by 2
x = 1.5
Therefore your answer is C or D (look at the picture)
