The equation of required line in slope-intercept form is:

y=\frac{3}{4}x-5

Step-by-step explanation:

We are given the points (4,-2) and (8,1) we need to find the equation of a line that connect the two points. We need to find equation of line in slope-intercept form.

The standard equation of slope-intercept form is:

y=mx+b

m is slope and b is y-intercept

  • Finding slope:

Using formula: Slope=\frac{y_2-y_1}{x_2-x_1}

Putting values:

x_1=4, y_1=-2, x_2=8 and y_2=1

Slope=\frac{y_2-y_1}{x_2-x_1}

Slope=\frac{1-(-2)}{8-4}

Slope=\frac{1+2}{4}

Slope=\frac{3}{4}

So slope is: Slope=\frac{3}{4}

  • Now finding y-intercept:

Using point (4,-2) and slope Slope=\frac{3}{4}

y=mx+b\\-2=\frac{3}{4}(4)+b\\-2=3+b\\b=-2-3\\b=-5

So, value of y-intercept is -5

The equation of required line is:

y=mx+b\\y=\frac{3}{4}x-5

So, the equation of required line in slope-intercept form is:

y=\frac{3}{4}x-5

Customers can pick their own apples at well orchards. They pay $6 to enter the orchard and $2 per pound for the apples they pick
Anvisha [2.4K]
Y=6+2x

Since y equals the total cost, it will be on its own in the equation. 6 dollars is a set amount, meaning that no matter how many apples they pick it’ll stay the same. HOWEVER, the cost will change depending on how many pound of apples they get

Every pound of apples is equal to 2 dollars, and since x stands for pounds of apples, it’ll be ( ex: x = 2, so 2x = 2(2) = 4)

So the equation will be y = 6 + 2x

I hope this helps
