1. A line goes through the points, (8,9) and (-2, 4)
2. Line A is represented by the equation, y=1/4x + 5.
I NEED THIS BY TODAY PLZ...................
a Slope=y2-y1 divided by x2-x1
b Point-slope is the general form y-y₁=m(x-x₁) for linear equations. It emphasizes the slope of the line and a point on the line (that is not the y-intercept).
c This can be done by calculating the slope between two known points of the line using the slope formula. Find the y-intercept. This can be done by substituting the slope and the coordinates of a point (x, y) on the line in the slope-intercept formula and then solve for b.
This is all I could find for you, sorry if this is not enough.
