Question

write the equation of the line that has a y-value that increases by 4 for every x that increases by 1. it also crosses the y-axis at -2

a. y=4x-2
b. y=1/4x-2
c. y=2x+1/4
d. y=2x-4

Answer 1

slope of the line= 4
to also passes through the point(-2,0)
plug these values into
y-y1 = m(x-x1)
and simplify

Answer 2

how do you plug the values in

Answer 3

m = slope = 4, (x1,y1) = (-2,0)

Answer 4

simplify ?

Answer 5

example of simplifying:


y = 3(x - 4) + 8
y = 3x - 12 + 8
y = 3x - 4

Answer 6

sorry i mixed up values of x and y x1= 0 , y1 = -2

so its y - (-2) = 4(x - 0)

Answer 7

Write the equation of the line that has a y-value that increases by 4 for every x that increases by 1. It also crosses the y-axis at –2.

Answer 8

rearrange the equation in my last post and you'll get one of the options
