Answer:
D. x=7√3 , y=4√2
Step-by-step explanation:
<em>Step 1: Lets assume an imaginary line from A to B to make the triangle ABC( (refer to the attached image).</em>
AB = 4
BD = 3
<em>Step 2: Find the value of y by the sin formula.</em>
opposite = 4
adjacent = BC
hypotenuse = AC
sin (angle) = opposite/hypotenuse
sin (45) = 4/AC
√2/2 = 4/AC
AC = y = 4√2
<em>Step 3: Find the value of x</em>
Tan (45) = opposite/adjacent
1 = 4/CB
CB = 4
x = CB + BD
x = 4 + 3
x = 7
Therefore, the answer is D where x = 7 and y = 4√2

Answer:
y = 3x - 5
Step-by-step explanation:
We know that the equation 'y = 3x + ?' intersects the point (1, -2). This means that when x = 1, y = -2 in out equation above. To solve this just plug in the x and y values to get '?'.
Now that we know '?' is -5, we write it back into slope intercept form, so our final answer is y = 3x - 5
