Explanation
Step 1: Find the slope of the given line
The equation of the given line is:
y=x
Comparing this with the slope-intercept form y=mx+c (where m is the slope), we get:
m1=1
Step 2: Determine the slope of the parallel line
Since parallel lines have identical slopes, the slope (m2) of our new line will also be:
m2=1
Step 3: Use the point-slope form to find the equation
The line passes through the point (x1,y1)=(2,5). Using the point-slope formula:
y−y1=m(x−x1)
Substitute m=1, x1=2, and y1=5 into the formula:
y−5=1(x−2)
y−5=x−2
y=x−2+5
y=x+3
Correct Answer
The correct option is (a) y=x+3.
