If you know the slope and x-intercept, writing the equation to a line is easy. For example, if you know the x-intercept to be 3, and the slope to be 2, then you plug it into the equation y=mx+b. At the point where the line hits the x-intercept, the y-value is 0, meaning you actually have a data point (3,0). Plug this into your equation: 0=3(2)+b 0=6+b -6=b b=-6 Then you put the equation together, as you know m and b: y=2x-6
The slope intercept equation also called the y intercept equation. It isy=mx+b in which x and y are coordinates, m is the slope of the line, and b is the y-intercept. so b would be the y-coordinate that intersects the y-axis.
By differentiating the answer and plugging in the x value along the curve, you are finding the exact slope of the curve at that point. In effect, this would be the slope of the tangent line, as a tangent line only intersects another at one point. To find the equation of a tangent line to a curve, use the point slope form (y-y1)=m(x-x1), m being the slope. Use the differential to find the slope and use the point on the curve to plug in for (x1, y1).
y - 2x is not an equation. If that is supposed to be y = 2x then the slope is 2. Or, written as a slope, would be 2/1
The straight line equation would depend on the slope which has not been given.
Slope Intercept form is meant for a line, so if you know the slope m in the equation y=mx+b then with a given point say (3,4) and say the slope of the line was 2 then the equation would read y=2x+4.
The equation of: y = 5x-3 would satisfy the given conditions.

Slope is the "steepness" of a line. If the line is on a grid, it can be calculated by dividing rise/run. If the line is given in the form of the equation y = mx + b the slope is the value of m.
The equation of a straight line is: y = mx+b whereas m is the slope and b is the y intercept
The equation then would be y = 13x
A normal slope-intercept form equation would read: y = mx + b The slope of an equation is also known as 'm'. The y-intercept would count as 'b'. So in a random equation such as: y= 5x + 6 '5' would be the slope and '6' would be the y-intercept.
This is simple algebra. You should know that parallel lines have the same slope. So you would take the slope of the line that is given to you and set it up in the equation y= mx + b. m stand for your slope and you would take the point that it gives you (3, -1) and plug it into y = mx + b (along with your slope) and solve for b..once you've solved for b, you can set up your equation because you know your slope (m) and y-intercept (b). If you are having trouble finding the slope, just solve the equation for y. Get y on one side of the equation. The number that is with x will be your slope. Good luck!
the equation is y=mx+b so this would be y=1x+4.
I assume you mean y = -6. The slope of this would be zero since it is a horizontal line. For the equation x = -6, the slope would be infinite since this is a vertical line.
