Please help with question 10

Answer 1

equation of the line is y=x+1

Explanation:

the equation of a line has the form y = mx + b

while m is for the slope and b is for the y-intercept.

you can see from the graph that the line intercepts the y-axis at y=1 this is the b.

you can get the slope of the graph by taking two points from the graph lets say (1, 2) and (3, 4) then using this formula:

`m = (y_(2)-y_(1) )/(x_(2)-x_(1) )`

in our case it will be:

`m=(4-2)/(3-1) = (2)/(2)=1`

then just substitute the values for m and b.
