Respuesta :

The answer is B because the equation is y=mx+b, where m is the slope and b is the y intercept. In this case m or the slope is -4 and the b or the y intercept is 1 so then just substitute them in and there is your answer

B. Y=-4x+1

We know that a equation of the straight line in the slope-intercept by is given as: y = mx + c Where (m) indicates the slope of the line and c is the y-intercept

In Mathematics, the  slope of the line is the change in y coordinate with respect by the change on x coordinate. The net change in y-coordinate is represented to the Δy or the net change in x-coordinate is represented by Δx.

How do you calculate the slope of an equation?

y = m x + b m known for the slope or b known for the y-intercept to the line. The steps to write this equation, we have 2 points are below. 1st, let's call our points Point 1 with coordinates ( x 1 ​, y 1 ​) and Point 2 with coordinates ( x 2 ​, y 2 ​). Now, we'll find the slope.
