Well, the equation 4x-y=8 is equivalent to the equation y=4x-8, so the slope would be 4.
4x-2y = 10 -2y = -4x+10 y = 2x-5 which is now in slope-intercept form
okay, so to find this the format of the equation is y=mx+b, where m is the slope, and b is the y-int. 4x-3y=6 simplified to that format is: y=1.3333...x+2, so the slope is 1 and 1/3, and the y-int. is 2.
Slope intercept form looks like y=mx+b, so we want to get y on on side by itself. -4x+2y=2 Add 4x to both sides: 2y=2+4x Divide both sides by 2: y=1+2x or y=2x+1
4x+5y = 7 5y = -4x+7 y = -4/5x+7/5 in slope intercept form So the slope of the perpendicular line is plus 5/4
Slope-intercept form: y = mx + b, where m is the slope and b is the y-intercept.By using the slope, m = 4 and the point (x1, y1) = (2, 1), write the point-slope equation of a line:(y - y1) = m(x - x1)(y - 1) = 4(x -2)y - 1 = 4x - 8 add 1 to both sidesy = 4x - 7Thus, the slope-intercept form is y = 4x - 7.
