Answer:

y = 4.125x + 496.25

Step-by-step explanation:

Set the data up as points. Then deal with the points.

Givens

(30,620)

(70,785)

y2 = 785

y1 = 620

x2 = 70

x1 = 30

Formula

Slope = (y2 - y1) / (x2 - x1)

Solution

Slope = (785 - 620)/(70 - 30)

Slope = 165 / 40

Slope = 4.125

===================

Now you need the y intercept. Either one of the two given points will give you that.

y = 620

x = 30

m = 4.125

y = mx + b

620 = 4.125*30 + b

620 = 123.75 + b

620 - 123.75 + b

b = 496.25

Evaluate. 102+6⋅7+8 70142150190
Aloiza [94]
Hi.

102+6(7)+8  (your equation)
102+ 42+ 8  (since the order is PEMDAS, multiplication has to go first. 6x7=42
144 + 8        (since you go left to right, 102 +42 has to be 1st. Answer= 144)
152              (now the only thing left is 144 + 8, so do that. Answer= 152.)

Since that's the last step, 152 will be your answer. 

Hoped I helped and if you need anymore you could always ask me~
