Question

A line passes through (-2, 3) and has a slope of 0.2. Write an equation of the line.

O y = 0.2x - 3.4
O y = -0.2x + 3.4
O y = 0.2x + 3.4
O y = -0.2x - 3.4

Answer 1

y = 0.2x + 3.4

Explanation:

Slope intercept form of line is

y = mx + c

where

m = slope

c is y intercept

given that slope is 0.2 thus, m = 0.2

now equation of line

y = 0.2x + c

now we substitute value of x and y ( (-2, 3) in this equation as given that the given point passes through the line

3 = 0.2*-2 + c

3 = -0.4 + c

c = 3+0.4 = 3.4

put c = 3.4 in equation

y = 0.2x + c

y = 0.2x + 3.4

Thus,

third option , y = 0.2x + 3.4 is the correct answer
