There is a single point which is a solution to the linear equation y-3=1/2(x+4) that is obvious because the equation is in point slope form. There are an infinite number of points that are not so obvious. Find the coordinates of the obvious point, and then find two additional points.

    y−3= 1 2 (x+4) y=0.5x+5

    its a funny question i would say that the point (-4,3) is the most obvious :- x = 4 when y = 3 because -4 makes the right side zero and 3 makes left side 0 3 - 3 = 0.5(-4+4) 0 = 0

    you can find 2 more points by putting x = 0 and finding y , and vice versa

    @welshfella math is my worst enemy right now.. I got (-4,3) but I don't get how to get 2 additional points..

    y - 3 = 0.5(x + 4) let x = 0 y - 3 = 0.5(0 + 4) y - 3 = 0.5*4 y - 3 = 2 so what is y ?

    and to get another point plug in y = 0 into the equation and solve for x

    y - 3 = 2 add 3 to both sieds y - 3 +3 = 2 + 3 y = 5 so another point is (0,5)

    when y = 0 0 - 3 = 0.5(x + 4) -3 = 0.5x + 2 solve for x
