Find the value of r so that the line passes through (9,13) and (5,r) has a slope of m=1/2.

R=11.  This is because you can use the point slope formula.  y = mx + b.  Plug 9 in for x and 13 in for y.  The slope of 1/2 is m.  You will then find b which is the y-intercept.  Then rewrite the equation as y=1/2x+8.5.  Plug 5 in for x and then simplify the equation.  You will discover that y, which is r, is 11.

0=6x+2y+10 is equivalent to the simplified form: y= -3x - 5• parallel lines always have the same slope, different y intercept knowing this, we can say the slope, or m of the line parallel to y= -3x - 5 is -3.m= -3 hope this could !
