Which equation does the graph below represent? (1 point)

a coordinate grid is shown. the x-axis values are from negative 5 to positive 5 in increments of 1 for each grid line, and the y-axis values are from negative 15 to positive 15 in increments of 3 for each grid line. a line is shown passing through the ordered pairs negative 4, 12 and 0, 0 and 4, negative 12.

y = fraction negative 1 over 3x

y = −3x

y = 3x

y = fraction 1 over 3x

The equation of the graph that is represented is:

We know that the equation of a line passing through two points (a,b) and (c,d) is calculated by the using the two-point formula:

From the graph we observe that the line passes through (-4,12) and (0,0)

Hence, the equation of line is:

the slope of the line is 60

one point on the line is (40,10)

step-by-step explanation:

in the equation outside the parenthesis the equation always tells you the slope. in this case it is 60.

in the parenthesis is also says 40 which is x because it is near the x and 10 is y because it is near y.

the simplified form is

step-by-step explanation:

we want to simplify the expression,

let us change the middle bar to a normal division sign to obtain,

we multiply the first fraction by the reciprocal of the second fraction to obtain,

we factor to obtain,

we cancel the common factors to get,

we simplify to get,

the correct answer is b
