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

The equation of the line is

The y - intercept of the equation is

Explanation:

Given that the equation of the line is and the slope is

Equation of the line:

The equation of the line can be determined using the formula,

Substituting the point (-1,4) and the slope , we get,

Simplifying, we get,

Thus, the equation of the line is

y - intercept:

The y - intercept of the equation is value of y when x = 0

Hence, substituting x = 0 in the equation , we get,

Thus, the y - intercept of the equation is

on a coordinate grid, point a is at (−4.0, −2.4) and point b is at (4.0, −2.4). point b is a reflection of point a across the –axis. input either a lowercase x or i think is the right awnser

step-by-step explanation:

hello from mrbilldoesmath!

answer:

25x^2 + 90x + 84

discussion:

mn(x) = m(n(x)) = m( 5x + 9) =

(5x + 9)^2 + 3 =>

25x^2 + 90x + 9^2 + 3 =

25x^2 + 90x + 84                 (as 9^2 = 9*9 = 81)

which is the second choice

p.s.   i'll be on vacation from friday, dec 22 to jan 2, 2019. have a great new year!
