What is the slope of this line?
2 answers:
Answer:
y = 3x + 4
Step-by-step explanation:
The line passes through points (-3, -5) and (0, 4)
The slope of the line = change in y-axis ÷ change in x-axis
i.e the slope = =
= 3
Taking another point (x, y) on the line,
The slope = = 3
Simplifying the equation above gives;
y - 4 = 3x
y = 3x + 4 (equation of the line)

Answer:
c
Step-by-step explanation:
y = x + 2 → (1)
2y = 5x + 4 ( divide through by 2 )
y = x + 2 → (2)
the 2 equations are the same and will have infinitely many solutions

Q2:
The point-slope form of an equation of a line:
m - slope
The formula of a slope:
We have the points (4, 6) and (6, 10). Substitute:
<em>use distributive property</em>
<em>add 6 to both sides</em>
<em>subteact 2 from both sides</em>
Q4:
The slope-intercept form of an equation of a line:
m - slope
b - y-intercept
Put the slope m = 3 and the coordinateso f the point (-2, 6) to the point-slope form of an equation of a line:
<em>use distributive property</em>
<em>add 6 to both sides</em>
