Question

I need help with this question please

Answer 1

Use y = mx + c
M = change in y/change in x
From point (2,4) the y distance from the point to the line is 1, the x distance is 2.
1/2 gives the gradient, a half.
C is the y intercept, where the line crosses the y axis at x = 0, it’s 4.
y = 0.5x + 4

Answer 2

y=1/2x+4

Explanation:

To find the formula of a line with slope intercept form, you need to know the slope of the line and the y intercept (where the line crosses the y axis, or where x is 0). The y intercept is visibly at (0,4). To find the slope of the line, you need to find how much the line "rises" in a certain amount of "run". You can see that the line moves two to the right for every one unit it moves up, meaning that it has a slope of 1/2. Plugging this into the slope intercept form, or y=mx+b, where m is the slope and b is the y intercept, you get:

y=1/2x+4

Hope this helps!
