How do you find x intercept?
to find the y-intercept you plug in your x and y values in to the equation of y=mx+b. b is the y intercept and m is the slope. To find the x-intercept, set y = 0, and find value of x that satisfies the equation. If it is a line in the form y=mx+b, then the x-intercept will be at x= -b/m
How do you find the straight line equation passing through the points -7 -3 and -1 -4?
First find the slope and then use the fact that y = mx+c where m is the slope and c is the intercept on the y axis to find the equation. Slope: -4 - -3 over -1 - -7 = -1/6 Equation: y = -1/6x -25/6 or 6y = -x -25
What is the equation that show the relationship between coordinates of points on a line called?
It is a straight line equation in the form of y = mx+c whereas m is the slope and c is the y intercept
How do you find the scale factor of the exponential equation?
m=24*(1.135)*1
When given an equation of a line an a point not on that line what are the steps to writing an equation that's through that point and parallel to that line?
If you represent the original straight line on a graph using Cartesian co-ordinates, it's equation will be y=mx+c where y and x are the variables and m and c are constants. (m will equal the gradient of the line. c will be the point where the line cuts through the y axis). Your new line, parallel to the original will be y=mx +c +d where d is the vertical distance between the point and the original line.
