Question

A line has a y-intercept of 4 and a slope of 8/7. Find the equation of the line.


A. y = 4x + 8/7


B. y = 4x - 7/8


C. y = 8/7x + 4


D. y = 7/8x - 4

Answer 1

y-intercept of 4 means when x=0 y=4, you have a point (0,4), and the slope 8/7

Answer 2

use the point-slope form
\[\Large{
y-y_1=m(x-x_1)
}\]

Answer 3

\[\large{
y-(4)=\frac{8}{7}(x-0)}\]

Answer 4

thanks :D

Answer 5

no problem
