Question

write an equation of a line with the given slope and y-intercept. m = –2, b = 4 y = 4x – 2 y = –2x – 4 y = -1/2x 4 y = –2x 4

Answer 1

y = mx + b

m = -2, b = 4

y = -2x + 4

Answer 2

`\text{The equation of line is }y=-2x+4`

Explanation:

Given the values of m=-2, b=4

we have to write an equation of line with above values.

As the general equation of straight line is

`y=mx+b`

where m is the slope and b is y-intercept

Substitute the values of m and b in above equation

m=-2, b=4, we get

`y=-2x+4`

which is the required equation of line.
