how do you make the equation if x is -2 and 6 and y is 6 and -10, and find the value of y if x is -10 and find the value of x if y is 4
You can always find the equation of a line if you know its slope and the coordinates of a point on the line or coordinates of two points on the line. Standard form of equation for straight line:
y=mx+b, with m=slope, and b=y-intercept. After you get the equation, you can solve for any value of x or y.
for given problem, two points are given.
find the slope=∆y/∆x=y1-y2/x1-x2=(6-(-10))/(-2-6)=16/-8=-2
To find y-intercept, plug in (x,y) coordinates from one of the points into standard form of equation and solve for b.
Using first given point,
