Answer:
Option A is correct
reflection across the x-axis
Step-by-step explanation:
The rule for reflection across x-axis is given by:
As per the statement:
The coordinate of triangle ABC are:
A(−4,−3) , B(−7,1) and C(−1,−1).
The coordinate of triangle A'B'C' are:
From the given diagram we have;
A'(-4, 3), B'(-7, -1) and C'(-1, 1)
Apply the rule of reflection across x-axis on ABC we have;
Therefore, the reflection results in the transformation of △ABC to △A'B'C' is, reflection across the x-axis

Answer:

Step-by-step explanation:
Where the graph crosses the x- axis the y- coordinate is zero.
Let y = 0 in the equation and solve for x
- 4(0) = 15 - 5x, that is
15 - 5x = 0 ( subtract 15 from both sides )
- 5x = - 15 ( divide both sides by - 5 )
x = 3 ← x- intercept ⇒ (3, 0 )
Where the graph crosses the y- axis the x- coordinate is zero.
Let x = 0 in the equation and solve for y
- 4y = 15 - 5(0), that is
- 4y = 15 ( divide both sides by - 4 )
y = - 
← y- intercept ⇒ (0, - )
