Answer:
y= 7/10x -1
Step-by-step explanation:
Assuming you want the equation is slope intercept form, this is the format for slope intercept: y=mx+b. Since you have the slope, this is your current equation: y=7/10x+b. Next, you want to find the y-intercept. So, plug in the coordinate to the equation. This is what it should look like: -1=7/10(0) +b/ Multiply 7/10 by 0 to get 0. So, here is what you're left with: -1=b. -1 is your y-intercept. Go back to your original equation and plug in the -1. This is your final answer: y= 7/10x-1. Hope this helped!
