An equation of a line through (2, 4) which is perpendicular to the line y = -2x + 1 has slope:
and y-intercept at:

slope: 1/2. y-int: 3

Step-by-step explanation:

for slope: the slope for a perpendicular line is the negative reciprocal. so -2 flipped is -1/2 and adding on a negative will cancel the original one so 1/2.

for y int: use the new slope and the point given to figure it out.

4 = 1/2(2) + b --> 4 = 1 +b --> b = 3

step-by-step explanation:

let

we know that

the y-intercept is the y-coordinate of the point when the value of x is equal to zero

so

the y-coordinate of the point a is the y-intercept

the answer part a) is

the value of y-intercept is

part b) find the slope m

we know that

the value of the slope is equal to

substitute the values

therefore

the answer part b) is

the value of the slope is equal to

the general answer is

the slope is

the value of y-intercept is
