Find the equation for the line that passes through the point
Find the equation for the line that passes through the points (-6,9) and (10,6). Give your answer in point-slope form. You do not need to simplify.
Solution
Given points (-6,9) and (10,6).
Need to find the equation for the line that passes through the points (-6,9) and (10,6) in point-slope form.
point-slope form of a line is y = mx + c
where m - slope and c is y-intercept.
Slope(m) = Change in y/Change in x
= (6-9)/(10-(-6))
= -3/16
\'c\' can be obtained by substituting m = -3/16 and a point(x,y) = (-6 ,9 ) in y = mx + c
y = mx + c
9 = (-3/16)(-6) + c
9 = 18/16 + c
9 - (18/16) = c
c = (16*9-18)/16
c = 126/16
c = 63/8
Slope-intercept form is y = mx + c
y = (-3/16)x + (63/8)
Therefore, required equation in Slope-intercept form is y = (-3/16)x + (63/8).
