Answer:
1. slope is 7 and y-intercept is 9
2.slope is -5 and y-intercept is -2
3. slope is 3 and y-intercept is 1
Step-by-step explanation:
The standard equation of a line in slope form is;
y=mx + b where m is the slope and b is the y intercept.
In question 1.
y=7x + 9
slope is 7 and y-intercept is 9
In question 2
y= -5x - 2
slope is -5 and y-intercept is -2
In question 3
y= 3x + 1
slope is 3 and y-intercept is 1
