Which of the following is equation of a line that passes through (-2,1) and (-4,-3)?

Step-by-step explanation:

The slope-intercept form of an equation of a line:

m - slope

b - y-intercept

The formula of a slope:

=======================================

We have the points (-2, 1) and (-4, -3). Substitute:

Put the coordinates of the point (-2, 1) to the equation:

          add 4 to both sides

Finally:

answer: i believe its b. if you sound out the sentences that sounds wrong.

f(x) is the value of the function. b is the value of the function when x equals zero or the y-coordinate of the point where the line crosses the y-axis in the coordinate plane.
