Answer: y = 2x - 7
Explanation:
Slope-intercept form is y=mx+b
Substitute variables with their given values.
y = 2x + b
In order to find the y-intercept, or b, we can plug the point provided, (4,1) , into y = 2x + b and solve for b.
1 = 2(4) + b
1 = 8 + b
-7 = b
Now we can put the y-intercept into the equation, and get y = 2x - 7 .
