Answer:
6. Slope = 2
7. y-intercept = 5
8. Equation: y = 2x + 5
Explanation:
Question 6
To find the slope of a line, define two points on the line:
- (x₁, y₁) = (0, 5)
- (x₂, y₂) = (1, 7)
Substitute these values into the slope formula and solve for m:
Therefore, the slope of the graph is
.
Question 7
The y-intercept is the y-value of the point at which the line crosses the y-axis.
From inspection of the given graph, the y-intercept is
.
Question 8
Slope-intercept form of a linear equation:
Where:
Substitute the found slope and found y-intercept into the formula to create an equation for the line:
