Question
Find the y-intercept of the following equation. Simplify your answer.
y = 9x + 7
- 7
- 8
- 5
- -5
Hint:
Constant part of standard equation y = mx + b , which is b is y intercept
The correct answer is: 7
Given y = 9x + 7
The given equation is in slope-intercept form i.e., y = mx + b, where b is the y-intercept and m is the slope.
Step 1 : finding b In y = 9x + 7,
here b = 7
So , the y-intercept which is = b is 7.
put x = 0 , in the given equation and solve for y , you will get y intercept .
