The questions is "A linear relation passes through the points (-40,19) and (24,91). Determine equations for the relation in slope intercept form, general form and slope point form." I am having trouble convering the slope intercept form which is y=1.125(x)+64 for the points provided, to general form. Ax+By+C=0 is general form and because the slope is 1.125 or 1.1/8 i am having trouble converting so that the numbers are whole.
