Question

Identify the function shown in this graph. AN -5 4 3 2 1 o A. y = 3x - 2 B. y = 3x + 2 C. y = -3x - 2 D. y = 3x - 2

Answer 1

Slope intercept form:

y=mx+b

Where:

m= slope ( y variation/ x variation)

b= y-intercept (where the line crosses the y-axis)

By looking at the graph we can see that the line crosses the y-axis at -2.

b=-2

slope = rise/ run= 3/1 = 3

Equation:

y= 3x-2
