( 2 , 5 ) and ( 26 /3 , 0 )
Step-by-step explanation:
Find the equation using the two points.
Use y = m x + b to calculate the equation of the line, where m represents the slope and b represents the y-intercept. To calculate the equation of the line, use the y = m x + b format.
Slope is equal to the change in y over the change in x , or rise over run.
The change in x is equal to the difference in x-coordinates (also called run), and the change in y is equal to the difference in y-coordinates (also called rise).
Substitute in the values of x and y into the equation to find the slope.
Multiply the numerator and denominator of the complex fraction by 3 .
Finding the slope m .
Find the value of b using the formula for the equation of a line.
Find the x-intercepts.
To find the x-intercept(s), substitute in 0 for y and solve for x .
solve the equation
x-intercept(s):
Find the y-intercepts.
To find the y-intercept(s), substitute in 0 for x and solve for y .
y-intercept(s):
