help asap please im failing

Step-by-step explanation:
The y intercept is when x=0 what is the y value.
When x=0, the y intercept is 1.
b. A gradient is the slope of the line. We need to find the rise and run of the line between two points.
Let use points 0,1 and 1,3
Our y values rise by 2 values and our x values change by 1 value so our slope is
[tex] \frac{2}{1} = 2[/tex]
Answer:
a. At the y-intercept,x=0
This implies the y-intercept=1
b. Taking points (0,1) and (1,3), the gradient of the line is given by (3-1)/(1-0) =2/1 =2
