Question

Find the equation in slope-intercept form of a line with slope –2 and y-intercept 4.

Question 10 options:

a)

y = -2x


b)

y = 4x -2


c)

y = -2x+4


d)

y = 2x-4

Answer 1

Answer:

c)

Step-by-step explanation:

-2 is the slope so that y equals -2x and the y intercept is positive 4 so that the equation is y=-2x+4

Answer 2

Answer:

c)  y = -2x+4

Step-by-step explanation:

The slope intercept form of a line is

y = mx+b  where m is the slope and b is the y intercept

Substituting in

y = -2x +4
