5x - y = 20
Step-by-step explanation:
The standard form of a line is written in the form: ax + by = c. But, let's first find the slope-intercept form: , where m is the slope and b is the y-intercept
Here, we know that m = 5, so let's put that in: .
However, we don't know b. So, let's use the point given (4, 0), and put in 4 for x and 0 for y to solve for b: โ
So, the equation is: . Now, we need to change this to standard form:
Add 20 to both sides and subtract y: 5x - y = 20.
Hope this helps!
5x - y = 20
Step-by-step explanation:
y = mx + c
0 = 5(4) + c
c = -20
y = 5x - 20
5x - y = 20
