Two equations are shown equation a: y=-5x-3, equation b: y=4x+5 which statement best compares the graphs of the two equations.
both are linear
both are non linear
equation a is nonlinear and equation b is linear
equation a is linear and equation b is nonlinear

Both are linear

Step-by-step explanation:

Each equation contains the variables x and y to the first power. Also, there are no products of variables. In addition, each equation is in the form y = mx + b which is the slope-intercept form of the equation of a line. Therefore, both are linear equations.

let x be the money she spent so that she can earn the free t-shirt.

since, she already spent $112.49

⇒

also, as per the statement: jennifer must spend $250 or more in order to qualify for a free t-shirt at the store.

then,

we have an inequality i.,e

subtract 112.49 from both sides we get;

therefore, $137. 51 more money does jennifer need to spend so that she can earn the free t-shirt

the formula of a slope:

we have the points (-2, 7) and (2, 3). substitute:
