Solve the following system using elimination:
{x - 2 y = -23 | (equation 1)
{x - y = 7 | (equation 2)
Subtract equation 1 from equation 2:
{x - 2 y = -23 | (equation 1)
{0 x+y = 30 | (equation 2)
Add 2 × (equation 2) to equation 1:
{x+0 y = 37 | (equation 1)
{0 x+y = 30 | (equation 2)
Collect results:
Answer: {x = 37 , y = 30
Answer:
1. The slope of the line is 7/3
2. y intercept is -3
3. y= 7/3x -3
Step-by-step explanation:
To find the slope of the line you use the equation y2-y1/x2-x1
y2 and y1 are y coordinates of the 2 coordinates on the same line that you want to find the slope of and the same with x2 and x1
The y-intercept is the point where the line crosses the y axis and x= 0
the equation of a line is y= mx+b
m= slope
b= y intercept
