Answer:

$y - x = 2$

Step-by-step explanation:

Given

Points (-2,0) and (-3,-1)

Required

Equation of Line

The first step is to determine the slope of the line; using the following formula

$m = \frac{y_2 - y_1}{x_2 - x_1}$

$Where\ (x_1,y_1) = (-2,0)\ and\ (x_2,y_2) = (-3,-1)$

$m = \frac{y_2 - y_1}{x_2 - x_1}$ becomes

$m = \frac{-1 -0}{-3 - (-2)}$

$m = \frac{-1}{-3 +2}$

$m = \frac{-1}{-1}$

$m = 1$

The next is to determine the equation of the line using any of the points

The formula is as thus;

$m = \frac{y - y_1}{x - x_1}\ or\ m = \frac{y - y_2}{x - x_2}$

Using $m = \frac{y - y_1}{x - x_1}$

$Where\ (x_1,y_1) = (-2,0)\ and\ m =1$

$1 = \frac{y-0}{x - (-2)}$

$1 = \frac{y-0}{x +2}$

$1 = \frac{y}{x +2}$

Multiply both sides by x + 2

$(x+2)*1 = \frac{y}{x +2} * (x+2)$

$(x+2)*1 = y$

$x+2 = y$

$y = x + 2$

Subtract x from both sides

$y - x = x - x +2$

$y - x = 2$

Hence, the equation of the line in standard form is $y - x = 2$

The highest score of the women’s basketball championship was Jessica Bradley. She scored 147 more points and Tina Hardtner her t

Rufina [12.5K]

Answer:

MAKE MY ANSWER BRILLINEST PLEASE:)

Step-by-step explanation:

LET:

j = the points that Jessica scored

t = the points that Tina scored

Jessica scored 147 more points than Tina:

j = t + 1497

Together, Bradley and Harner scored 1601 points:

j + t = 1601

by solving the system of equations:

j = t + 147

j + t = 1601

we find

j = 856 points

t = 707 points

Jessica Bradley scored 856 point.

Tina Harner scored 707 points.
