<h2>It's a reflection across the x-axis.</h2>Step-by-step explanation:
(x, y) → (x, -y)
It's a reflection across the x-axis.
<em>The reflection of the point (x,y) across the x-axis is the point (x,-y).</em>
Answer:
3x - 2 = 2y
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 )
Rearrange 3x + 5 = 2y into this form by dividing all terms by 2
x +
= y ← in slope- intercept form
with slope m =
Parallel lines have equal slopes and c = - 1, thus
y = x - 1 ← in slope- intercept form
Multiply through by 2
2y = 3x - 2 ← equation of line
