Use the formula y=mx+c (Eqn 1)
m=-3/4
The line passes through (8, -12) so insert these values into Eqn 1
==> -12 = -3/4*8+c (I use * to mean multiply)
==> c = -12 +3/4*8 = -12 + 6 = -6
So the eqn of the line is y = -3/4x -6
The y intercept is found when x=0.
==> y = -3/4*0 - 6 = -6
So the y intercept is the point (0, -6)
y = mx + b
-12 = ( -3/4 ) ( 8 ) + b
-12 = -6 + b
b = intercept = -6 <----------[ ANSWER ]--------------------
what is the horizontal line that passes through (-5,6)
It is: y = 5x+6
7x + 4 = - 67x = - 10x = - 10/7X-intercept: x = - 10/7There is no y-intercept. The graph is a straight vertical line passing through the point x=-10/7.It's parallel to the y-axis, so it never intercepts the y-axis.
y = 4
The slope intercept form is: y=mx+b where m is the slope and b is the y-intercept. Since you already know the slope, you can plug that into the equation. y=-3x+b The only thing left to do is to find out what b is. To do this, plug the x and y value of the point it goes through into the equation and solve for b. Good luck.
what is the horizontal line that passes through (-5,6)
The slope of a vertical line is undefined and so there cannot be a slope-intercept form of the equation.
It is: y = 5x+6
The equation is y = 5x - 15 or y = 5*(x - 3)
A sample equation could be y = 5/3x + 1, the x-intercept is 1 and the y-intercept is -1.
The equation in slope-intercept form would be y=-2x
Points: (4, -2) and (6, -3) Slope: -1/2 Straight line equation: y = -1/2x There is no y intercept.

Y intercept occurs where x=0. Substitute x=0 in this equation. Y = 2(0) Y = 0 For the x-intercept, substitute y=0: 2X = 0 X = 0 This is a line that passes through the origin. If the graph looks like y = ax + b, the y-intercept is at the point b (b can be positive or negative), and the x intercept is (-b/a).
