The function f(x) is shown in the graph. What is the equation for f(x)?
1 answer:
It's a linear graph, so we can use the slope-intercept form. Let's find the y-intercept first, which happens ar y = -3. Now let's find the slope. To do so, let's pick two points on the graph (relatively easy ones): (0, -3) and (5, -7).
Let's find the slope:
Let's write it in slope-intercept form. Recall that slope-intercept form is:
Where m = slope and b = y-intercept. We have all the parts, so let's write it:

Step-by-step explanation:
In the figure attached,
Vertices of the triangle ABC are A(-4, 4), B(-1, 4) and (-1, 2)
When we reflect this figure across a line y = 1
Vertices of the image triangle A'B'C' will be
Coordinates of A'
A(-4, 4) → A'[(1 + 5), 4]
→ A'(6, 4)
Coordinates of B'
B(-1, 4) → B'(-1 + 4, 4)
→ B'(3, 4)
Coordinates of C',
C(-1, 2) → C'[(-1 + 4), 2]
→ C'(3, 2)
Graph these points and join them to form the image triangle A'B'C'.
