Find the x- and y-intercepts of the graph of — 7x + 8y = 40. State your answers as

geniusboy [140]

Answer:

x-intercept is (40/7, 0) and y-intercept is (0, 5)

Step-by-step explanation:

x-intercept ==> y-coordinate is 0 ==> y=0

y-intercept ==> x-coordinate is 0 ==> x=0

because the function is 7x + 8y = 40

when y = 0 ==> 7x = 40 ==> x = 40/7

so the x-intercept is (40/7, 0)

when x = 0 ==> 8y = 40 ==> y = 5

so the y-intercept is (0,5)

Distance Formula: $d = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

Step-by-step explanation:

Step 1: Define

Point A (2, -1)

Point B (-4, 2)

Step 2: Find distance d

Simply plug in the 2 coordinates into the distance formula to find distance d.

Substitute [DF]: $d = \sqrt{(-4-2)^2+(2+1)^2}$
Subtract/Add: $d = \sqrt{(-6)^2+(3)^2}$
Exponents: $d = \sqrt{36+9}$
Add: $d = \sqrt{45}$
Simplify: $d = 3\sqrt{5}$
