A)
The slope-intercept form:
m - slope
b - y-intercept
The formula of a slope:
We have the points (2, 5.1) and (-1, -0.5). Substitute:
Therefore we have:
Put the coordinates of the point (-1, -0.5) ot the equation:
<em>multiply both sides by 2</em>
<em>add
to both sides</em>
<em>divide both sides by 2</em>

B)
We have the points (-2, 3) and (3, -4).
Calculate the slope:
Therefore we have:
Put the coordinates of the point (-2, 3) to the equation of a line:
<em>subtract
from both sides</em>
