The length of the unknown side is 17.5
Answer:
y=2/7x+9
Step-by-step explanation:
Slope-intercept form is written y=mx+b.
y= also known as f(x), and is always by itself in slope-intercept form.
m= the slope.
x= the variable written to the right of the slope.
b= the y-intercept.
We know that the slope is 2/7 and the y-intercept in the equation is 9. Therefore, we can plug these numbers into the equation. So...
y=2/7x+9
is the correct equation written in slope-intercept form.
Hope this helps!! Have an amazing day (^人^)
