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
A(-4, 2) and B(3, -2).
I will do number 2.
Let d(A, B) = distance between the two points.
d(A, B) = sqrt{(3 -(-4))^2 + (-2-2)^2}
d(A, B) = sqrt{(3 + 4))^2 + (-2-2)^2}
d(A, B) = sqrt{(7)^2 + (-4)^2}
d(A, B) = sqrt{49 + 16}
d(A, B) = sqrt{65}
Done!
