Answer:
The value of y is - ⇒ answer B
Step-by-step explanation:
- If a point lies on the graph of an equation, then it must to satisfy the
equation
- That means when you substitute the coordinates of the point in the
equation the left hand side will equal the right hand side
- The point (-6 , y) lies on the graph of the equation 5 y = 2 x - 4
- We need to find the value of y-coordinate of the point
- To do that substitute the value of x-coordinate of the point in the
equation
∵ 5 y = 2 x - 4
∵ x = - 6
∴ 5 y = 2(-6) - 4
- Multiply 2 by - 6
∴ 5 y = - 12 - 4
- Add like terms in the right hand side
∴ 5y = - 16
Divide both sides by 5
∴ y = -
The value of y is -
Referring the chart I attached, the slope is the ratio of rise to run
So we need to pick two points lying on the line to calculate the slope.
They would be (4,0) and (0,2)
That is for the slope
The y-intercept is where the line touches\crosses\intersects the y-axis...
It is clear from the figure that the line crosses the y-axis at (0,2)
so the<span> y-intercept is
</span>
