As we know,

now, let's plug the given values to find a² + b²
Answer:
C is the most reasonable answer because to add the system of equations together, you must make sure that one of the terms (whether it be the x or y value) can cancel out.
Step-by-step explanation:
Answer:
y=−4/3x+10
Step-by-step explanation:
Find the negative reciprocal of the slope of the original line and use the slope-intercept form y=mx+b to find the line perpendicular to 3x−4y=−2.
