Answer:

y+7 = 4/3(x-9)

Step-by-step explanation:

Point slope form of an equation of a line is

y-y1 = m(x-x1) where (x1,y1) is the point and m is the slope

y--7 = 4/3(x-9)

y+7 = 4/3(x-9)

Answer:

SLOPE INTERCEPT FORM: y = 4/3x - 19

POINT SLOPE FORM: y - (-7) = 4/3(x - 9)

Step-by-step explanation:

Point slope formula is y - y1= m(x - x1)

Insert the information:

➡️y - (-7) = 4/3(x - 9)

(this is point slope form)^

distribute.

➡️y + 7 = 4/3x - 12

move constants on the left side to the right, to get y = mx + b.

➡️y = 4/3x - 19

I didn't know if you just wanted point slope form or to make it slope intercept form, so here's both.

Write an equation for the line described in standard form with x-intercept 4 and y-intercept 5

stealth61 [152]

Answer:

Equation $( \frac{5}{4}) x + y = 5$ is in the standard dorm.

Step-by-step explanation:

Here, the x - intercept = 4 , so ( 4,0) is a point on the line.

and the y - intercept = 5, so ( 0,5) is a point on the line.

So, the slope of the equation is given as = $\frac{y_2 - y_1}{x_2-x_1 } = \frac{5 -0}{0-4} = -\frac{5}{4}$

Now, the SLOPE INTERCEPT FORM of an equation is :

y = mx + b: here m = slope and b = y- intercept

or, $y =-( \frac{5}{4}) x + 5$

Now, standard form is Ax +By = C

So, the standard form is $( \frac{5}{4}) x + y = 5$

Hence, the above equation $( \frac{5}{4}) x + y = 5$

is in the standard dorm.
