Let y = 0 to find the x-intercept(s).
0 = 45 − 4x
*Then subtract 45 from both sides*
-45 = -4x
*Next, DIVIDE both sides by -4*
-45
—— = x
-4
*NEXT, realize that TWO NEGATIVES MAKE A POSITIVE *
45. 4
——— = x {FLIP} x=——-
4. 45.
y-Intercept
Let x = 0 to find the y-intercept(s).
y = 45 −4(0)
NEXT, SIMPLIFY:
y=45
Answer:
y = -3/2x + 3
Step-by-step explanation:
slope-intercept form: y - y₁ = m (x - x₁)
y - 9 = -3/2 ( x + 4)
y = -3/2 x - 6 + 9
y = -3/2x + 3

Answer:
1440
Step-by-step explanation:
How one of my teachers said is 72 time 40 is 2880
and then 2880 divided by 2 is 1440. This is what my teacher said so I don’t know.
Step-by-step explanation:
solve the ineq first then plot on the number line so,
-2(4x + 5) ≤ 30
-8x - 10 ≤ 30
-8x ≤ 40
x ≥ -5
therefore, option A is correct.
