I assume you mean between the points (9, -3) and (4, 10): slope = change_in_y/change_in_x = (10 - -3)/(4 - 9) = 13/-5 = -23/5 = -2.6
If you mean: y = 12x-23 then the slope is 12 and the y intercept is -23
HOW TO FIND THE SLOPE AND Y-INTERCEPT OF A LINEto find the slope, you need 2 coordinates on the line. So, 2 sets of (x, y) which will be:(x1,y1) and (x2,y2) you will then perform the following to find the slope of the line(y2-y1)/ (x2-x1). (so you do y2-yi divided by x2-x1) This is how you find the slope.If you want to find the y-intercept (represented by the variable b), substitute one of your given points (from question 1) and your slope (which is represented by the variable m) into this equation:y= mx + bSo, you know the values of x, y (your coordinates) and m (your slope). Substitute the values to solve for b. Then, this will be your final equation of the line.Remember that if the lie goes down from left to right, the slope is negative. If the line goes up from left to right, the slope is positive.* Important To Remember*-If the line is horizontal, the slope is zero-If the line is vertical, the slope is UNDEFINED-If a line goes vertically on the x- axis the equation will be "x = that number that crosses the x- axis" since the line will not have a y-intercept since it doesn't cross the y- axis.*TIPS*When doing questions with slopes and y-intercepts, graph the line first!
Points: (13, 17) and (19, 23) Midpoint: (16, 20) Slope of required equation: 5/4 Its equation: 4y = 5x or as y = 1.25x Its distance from (0, 0) to (16, 20) = 4 times sq rt 41
If you mean y = 23x-7 then the slope is 23 and the y intercept is -7
It has no slope.
Slope=8 point=(-7,3)
Points: (0, 3) and (5, 23) Slope: 4 Equation: y = 4x+3
Points: (5, -2) and (4, 3)Slope: -5Equation: y = -5x+23
y=23
I assume you mean between the points (9, -3) and (4, 10): slope = change_in_y/change_in_x = (10 - -3)/(4 - 9) = 13/-5 = -23/5 = -2.6
It is: y = -23 which will be straight horizontal line parallel to the x axis
Two or more coordinates are needed to determine the slope of a line
If you mean points (x,y) : (-2, 7) and (2, 3) then the slope works out as -1 as the slope = (y2-y1)/(x2-x1) = (3-7)/(2 +2) = -4/4 = -1
If both lines are parallel then they will have the same slope but with different y intercepts
If you mean a slope of 6 and point of (-3, 5) then the equation is: y = 6x+23
If you mean: y = 12x-23 then the slope is 12 and the y intercept is -23
