Question

Identify the graphed linear equation.

Answer 1

C. y = -4x + 1

Explanation:

To find the equation for this graph in the formula of a linear equation, y = mx + b, you need 2 things:

1. the y-intercept, or b;
2. slope, or m

b is the y-intercept of the line, so in this case, it would be 1.

m is the slope in the form of
`(rise)/(run)`, from left to right using a point on the line. If the line goes down from left to right, the slope will be negative, or if the line goes up from left to right, the slope will be positive. In this case, the line goes down 4 and right 1, so the slope is
`-(4)/(1) = -4`.

Put it together, and you get this equation: y = -4x + 1
