A line passes through the point (7,9) and has a slope of 2.
Write an equation in slope-intercept form for this line.
Answer: y = 2x - 5
Step-by-step explanation:
slope- intercept form is always written as y = mx + b, where m = slope, and b is the y-intercept.
To find b, substitute the point and the slope into the equations, you will get:
y = mx + b
9 = 2(7) + b
9 = 14 + b
-5 = b
Plug in m and b into the equation, we get:
y = mx + b
y = 2x + (-5)
y = 2x - 5
write in standard form. y=−5/6x−8/3
[tex]y = - \frac{5}{6} x - \frac{8}{3} [/tex]
[tex]6 \times y = - \frac{5}{6} x\times 6 - \frac{8}{3} \times 6[/tex]
[tex]6y = - 5x - 16[/tex]
[tex]5x + 6y = - 16[/tex]
The equation is y=mx+b.
My question is, is ‘b’ supposed to be in decimal form or in fraction form??
Answer: both ways are acceptable
Step-by-step explanation: When writing equations of lines in this form,
we usually keep the "b" value or the constant term as a fraction.
However, if you prefer decimals, you can absolutely change
it to a decimal to visualize is better if you'd like, it's really your choice.
For example, if the equation of a line was y = -3/4x - 7/4, I could leave
it how it is or I could change the -7/4 to -1.75 giving me y = -3/4x - 1.75.
rate of change for y=-2x

the hire purchase of a car is 680000 naira. there is a deposit of 12.5 percent. the remainder is spread over 12 equal monthly instalment. find the deposit , calculate the remainder to be paid and find the amount of each monthly instalment to the nearest naira
Answer:
Step-by-step explanation:
I am not sure why there is no interest rate given as it is common that there will be an interest charge for a monthly installment plan.
Assuming it is an interest-free plan, the remainder payment is for an amount of:
680000*(1 - 12.5%)
= 680000*(0.875)
= 595000 naira
Dividing that into 12 equal monthly, each monthly installment is
595000/12 = 49583.33
~49583 naira

Which is the point-slope form of a line that has a slope of -4 and passes through point (-3,1)?
Hi!
The point-slope formula looks like this:
y-y1=m(x-x1)
in this case
y1=1
m=-4
x1=-3
plug in the values
[tex]\boxed{\boxed{\bold{y-1=-4(x-(-3)}}}[/tex]
Note:
For Point-Slope Form, we use a point that the line passes through and the slope of the line.
Actually, that's why it's called "Point-Slope Form" right? =)
Hope everything is clear.

Find the value of xx, yy, and zzz in the rhombus below.
Answer:
x = 13; y = 13; z = 18
Step-by-step explanation:
In a rhombus, opposite angles are congruent and consecutive angles are supplementary.
6x + 8 = 86
6x = 78
x = 13
7y + 3 + 86 = 180
7y + 89 = 180
7y = 91
y = 13
5z + 4 + 86 = 180
5z + 90 = 180
5z = 90
z = 18

x=13
y=13
z=18
