Answer:
EF, where E is at (1, 9) and F is at (2, 5)
Step-by-step explanation:
Slope = rise/run or y/x. In a coordinate, a point on a graph is represented as (x,y). When the slope is -4 (or -4/1), this means the y value will decrease (as it is negative) by 4 units, while the x value increases (as it is positive) by 1 unit. The line EF demonstrates the values (1, 9) and (2, 5). The difference between them is (1, -4) in (x, y) form.
Answer:
K = 5m+y/x
Step-by-step explanation:
Let's solve for k.
y=kx+1m(2−7)
Step 1: Flip the equation.
kx−5m=y
Step 2: Add 5m to both sides.
kx−5m+5m=y+5m
kx=5m+y
Step 3: Divide both sides by x.
kx/x = 5m+y/x
Therefore, k = 5m+y/x
