Answer:
y = 4x - 2
When y = 26, x = 7.
Step-by-step explanation:
Use the two points on the line to calculate the slope of the line, then use this slope and the y-intercept to write an equation for the line.
Slope formula:
We have these two points on the graph: (1, 2), (-1, -6).
Substitute these points into the slope formula and find the slope of the line.
The slope of the line is 4. Now, use the point-slope formula to write an equation for the line.
Point-slope formula:
- y - y1 = m(x - x1)
- y - 2 = 4(x - 1)
- y -2 = 4x - 4
- y = 4x - 2
To find the value of x when y = 26, substitute y = 26 into the equation and solve for x.
- 26 = 4x - 2
- 28 = 4x
- x = 7
