Step-by-step explanation:
Solve the inequality for x by finding a
, b
, and c of the quadratic then applying the quadratic formula.
Step-by-step explanation:
if you are given an equation of a form y=kx+b, k is gradient and b is y-intercept
in c you can write this equation as y=(2x/3)-2,so gradient = 2/3 and y-intercept =-2
in e:6y=2x+3
y=x/3+1/2,gradient = 1/3, y-intercept=1/2
Answer:
No
Step-by-step explanation:
To determine if (- 5, - 5) is a solution
Substitute x = - 5 into the inequality and compare answer to y
- 2(- 5) + 4 = 10 + 4 = 14 > - 5 ← the y- coordinate
Thus (- 5, - 5) is not a solution to the inequality
Graph C shows the line of slope
Answer: 
Step-by-step explanation:
The slope of the line is
Using the point (-2, 0) to substitute into point-slope form, we get the equation to be
