Answer:
a. y = 3
b. x = 1
c. y-intercept = 5
d. x-intercept = -2.5
e. 2
f. y = 2x + 5
Step-by-step explanation:
Based on the graph, we can see the point where x is -1, y = 3.
Based on the graph, we can see the point where y = 7, x = 1.
Based on the graph, we can see the y-intercept is 5.
Based on the graph, we can see the x-intercept is -2.5.
To calculate the slope of the line, I will be using the points (-1, 3) and (0, 5).
Slope = [tex]\frac{rise}{run}[/tex]
= [tex]\frac{5-3}{0-(-1)}[/tex]
= [tex]\frac{2}{1}[/tex]
= 2
The equation of a line is: y = mx + c where m is the slope and c is the y-intercept. Thus, the equation of the line in this case is: y = 2x + 5
