It's the equation of a line. We need only two points to the plot the graph.
Choice any two values of x. Put them to the equation of a line and calculate the values of y.
for x = 0:
for x = 5:
Answer:
B. x = 7, y = 4√2
Step-by-step explanation:
Drop a vertical from the upper left corner
This creates a rectangle and a 45-45-90 triangle
The bottom of the rectangle is 3
The legs of the triangle are 4
Therefor
x = 4 + 3
x = 7
For a 45-45-90 triangle
the hypotenuse = leg * √2
y = 4√2
