Answer:
x = 3
Step-by-step explanation:
Given
= = ( cross- multiply )
5x = 2(5 + x) ← distribute

3x = 10 ( divide both sides by 3 )
x = = 3
Answer:
Step-by-step explanation:
To find the slope of the graph, we use the expression below;
Slope =
We pick two points; (-2, 1) and (4, 4)
x₁ = -2,
y₁ = 1
x₂ = 4
y₂ = 4
Now insert the parameters and solve;
Slope = =
