Answer:
1. 4
2. m=3, b=-5
3. m=5
4. It should look like on the attached picture
Step-by-step explanation:
1. x-intercept is the value of x if y=0. Therefore,
if y=0
2. slope-intercept form is . Therefore, given the equation , m=3 and b=-5
3. From our solution in number 2 above, m=5
4. It should look like on the attached picture
