Answer:
m = 4
Step-by-step explanation:
equation of point slope formulae
[tex]y = mx + c[/tex]
m = slope , c = y-intercept
1) find the slope
* use the two coordinates given to find the slope
slope formulae:
[tex] \frac{y2 - y1}{x2 - x1} [/tex]
i) (4,7)
x1 = 4
y1 = 7
ii) (5,11)
x2 = 5
y2 = 11
substitute the values into the formulae
[tex]m = \frac{11 - 7}{5 - 4} [/tex]
[tex]m = \frac{4}{1} [/tex]
[tex]m = 4[/tex]
the slope = 4
