Answer:
y = (-3/2)x + 7
Step-by-step explanation:
3x + 2y = -4 (rearrange to slope intercept form y = mx + b)
2y = -3x - 4
y = (-3/2) x - 2
comparing this to the general form of a linear equation : y = mx + b
we see that slope of this line (and every line that is parallel to this line),
m = -3/2
if we sub this back in to the general form, we get:
y = (-3/2)x + b
We are still missing the value of b. To find this, we are given that the point (4,1) lies on the line. We simply substitute this back into the equation and solve for b.
1 = (-3/2)4 + b
1 = -6 + b
b = 7
substituting this back into the equation:
y = (-3/2)x + 7

Answer:
Triangle 2 is a transformation from Triangle 1, and has been reflected across the x-axis.
Step-by-step explanation:
We can conclude that Triangle 2 is a reflection across the x-axis because the x values stayed the same but the y values are negative.
In a reflection across the x-axis, the x values will stay the same. But, since it is flipped across the x-axis, the y values will become negative.
So, Triangle 2 is a reflection across the x-axis.
