Question

Which is the equation of the given line in slope-intercept form? y= -1/4 x +1 y= -4x+1 y=4x-1 y=4x=+1

Answer 1

Answer:

$y=4x+1$

Step-by-step explanation:

The line is shown in the attachment.

The slope of this line is given by: $m=\frac{y_2-y_1}{x_2-x_1}$

The line passes through (0,1) and (1,5)

Plug in the points to get:

$m=\frac{5-1}{1-0}=4$

The equation of this line is given by $y=mx +b$, where b=1 is the y-intercept.

From the graph the y-intercept is 1, because the line intersects the y-axis at (0,1).

Therefore the equation is $y=4x+1$
