a- Find the equation of the straight line that has slope m = 4 & passes through the point (-1, 6).

Question

b- Give a verbal description for the slope.
c- Find the horizontal and vertical intercepts.
d- Plot the line over the interval x = 0 to x = 2.
Taking set of points

Answer 1

a)  y-y₁ = m(x-x₁)  so y - 6 = 4(x +1)  or  y = 4x + 10

 

b) as x increases by 1 unit, y increases by 4. 

 

c)y intercept = 6; x intercept (when y=0) is 5/2

 

YOU can graph it using any two points you like.
