Question

Write an equation for the graph, where y depends on x.

Answer 1

y = -3x + 6

Explanation:

Equation of straight line is given by,

y = mx + b

m = slope of the line

b = y-intercept

From the graph attached,

m =
`\frac{\text{Rise}}{\text{Run}}`

=
`(-6)/(2)`

= -3

y intercept 'b' = 6

Therefore, equation of the line will be,

y = -3x + 6
