5. Standard Form
Sign In
Try using the Slope Formula and point-slope form to write an equation before solving for the x- and y-intercepts.
x-intercept: x=10
y-intercept: y=- 103
To determine the x- and y-intercepts of a line, we need to substitute 0 for one variable, solve, then repeat for the other variable. In this case, we haven't been given an equation, so we will need to use the given points to write one.
Substitute ( -5,-5) & ( 4,-2)
y= 0

x= 0
Add terms
1/b* a = a/b
LHS-5=RHS-5
a = 3* a/3
