What is the y-intercept of this line?

5

Step-by-step explanation:

The Y intercept is where the line crosses the Y axis when X = 0.

(X,Y) -> (0, 5)

The equation of that line looks to be Y = X + 5.

That equation I wrote follows the Y = mx + B format.

The +B is the Y intercept.

y=mx+c or y=mx+b

gradient = rise/run

= 1 ( sloped upwards)

y= (1x)+c

y=x+c

to find c, we have to input values for x and y

take one point from the line on the graph, suppose...

(x,y) :  (-3,2)

2=-3+c

5=c

y=x+5

to solve for y, x will always be 0

y=0+5

y=5

your answer is 228

step-by-step explanation:

add the top and bottom bases together, then divide them by 2, then multiply by the height.
