Answer:
Step-by-step explanation:
an equation is : y = 10x+b
calculate b : this line passes by : (7;1) when x =7 y = 1
so : 10(7)+ b=1
b= -69
so : y = 10x-69
For this case we have that by definition, the equation of a line of the slope-intersection form is given by:
[tex]y = mx+b[/tex]
Where:
m: It's the slope
b: It is the cut-off point with the y axis
How do we have to:
[tex]m = 10\\(x, y) :( 7,1)[/tex]
So, the equation is of the form:
[tex]y = 10x+b[/tex]
We substitute the point and find b:
[tex]1 = 10 (7)+b\\1 = 70+b\\b = 1-70\\b = -69[/tex]
Finally, the equation is of the form:
[tex]y = 10x-69[/tex]
Answer:
[tex]y = 10x-69[/tex]
