First you have to find the slope with the equation y2 - y1 / x2 - x1 , then once you have found the slope (slope = -2) you simply plug it into the point slope formula. y-0 = -2(x-5) solving it algebraically you should arrive at Y=-2x+10. (the 5 and 0 were plugged in are two of the X and Y points of the line which is why we plugged them into the X and Y values of the equation)
Yes. Parallel means same slope as original line. So it’s 2
X = √7²+4² by using Pythagoras Theory as the triangle is a right angled triangle
I believe the answer would be 6.96 cm
