Slope of a line segment can be demonstrated as rise/run. The amount a line rises or falls, divided by the amount the line "runs" or moves from left to right. This can be calculated by choosing any two points on the line and using the equation m = (<span>y2</span><span> - </span><span>y1</span>)/(<span>x2</span><span> - </span><span>x1</span><span>)</span>
Y = 5 - 3x....so sub in 5 - 3x for y in the other equation
5x - 4y = -3
5x - 4(5 - 3x) = -3.....distribute the -4 thru the parenthesis
5x - 20 + 12x = -3...add 20 to both sides
5x + 12x = -3 + 20...combine like terms
17x = 17...divide both sides by 17
x = 17/17
x = 1
now sub 1 in for x into either of the original equations to find y
y = 5 - 3x
y = 5 - 3(1)
y = 5 - 3
y = 2
check...
5x - 4y = -3
5(1) - 4(2) = -3
5 - 8 = -3
-3 = -3 (correct)
so ur solution is (1,2)
Answer: 0.06
Step-by-step explanation: subtract them and you'll get your answer
<span>If you divide 63 by 3 you get 21 which means that on Sunday she skied for 21 miles and On Saturday for 42 because she skied twice as many miles on Saturday.
</span>
Y=X-5 because if you algebraically find the rate per hour, you get 5.
