Answer:
a) 2
b) 1
c) y =mx+b
Explanation:
Slope = rise/run = Δy/Δx = 2/1 =2 [Δ means difference between 2 values]
To find slope we need to find by how many difference do the x and y increases or decreases. Here y increases by 2 and x increases by 1.
The constant just another way of asking y-intercept.
The slope-intercept form y=mx+b. [m=slope, b= y-intercept]
We will choose point (1,3) to input into the equation. You can use any point it would give the same answer.
3 = 2×1 +b
3 = 2 +b
b = 3-2
b = 1
