Identify the slope and y intercept. equation: y = 4x - 1 the slope (m) = the y intercept =

slope is 4

y intercept is -1

Step-by-step explanation:

Easiest way to remember is future is this;

y = mx+c  where m is the slope and c is the y intercept.

Try that with a few other examples and you could figure it out in seconds next time.

x = 10.1

step-by-step explanation:

all of the angles of a tirangle add up to 180º

180 - 65 = 115 (since we already know the value of one angle)

(2x + 7) + (8x + 7) = 115

(combins like terms) 10x + 14 = 115

(isolate the variable subtract 14 from both sides): 10x = 101

(find the variable divide both sides by 10): x = 101/10

x = 10.1
